Can you turn the light completely off?

    Very awesome Essential oil diffuser. It works really well. I bought a few different oils to use in it and it makes my room smell amazing. I thought it was going to blow out hot water vapor but it is actually very cool vapor and cool to the touch. The band just above the button controls changes colors and looks really cool. I am super happy with it and have had compliments from many friends and family about it and asking where to purchase one. It comes with a power cord, a measuring cup for filling, and a user manual.

    This is a great diffuser. It comes with a handy instruction manual which makes it easy to set up and use. The buttons on the base are touch buttons which is a cool feature. It stores up to 400ml of water which can let it run for hours. There are different light modes, you can cycle through various colors, or set it on one of the 7 colors - the colors are shown on the little light strip running around the base of the unit as well as on the top where the mist comes out. There are two mist settings (strong and weak). I haven't really noticed a difference between the two settings, but the mist that comes out is strong. I use brand named oils in this diffuser and I can smell the scent through our entire kitchen/living room downstairs. I would highly recommend this diffuser.

    I own quit a few diffusers, I like having different options. This diffuser I use in my living room since it is a little bigger. I have it placed on my table. It is easy to use and it diffuses great. The top part comes off that is where you put the water and the oil you want to use. There is a line marked to how full you fill the water up at. The buttons are on the front of the diffuser so you can turn it on or off and set the timer for how many hours you want it to run, plus it has an automatic shutoff. This diffuser can hold 400ml. The diffuser is not loud either which I like about it. I don't even notice its running.

     Tengo este humidificador desde hace unos días. Empezaré diciendo que estamos muy contentos con él y que lo volvería a comprar sin duda. Lo cierto es que tardó un tiempo en llegar (unas dos semanas), pero la espera ha merecido la pena. Viene en una caja de color cartón con los logos y dibujos. Aunque la caja no está mal, se podría mejorar, sobretodo pensando en la gente que lo compra para regalarlo. En cualquier caso lo importante está dentro. Allí nos encontramos el humificador, el transformador con su cable, un cazo para medir líquidos (y de paso vertirlos en el aparatejo) y unas instrucciones, que por cierto incluyen su correspondiente sección en castellano. Es decir, en la caja viene todo lo necesario para hacerlo funcionar, con excepción de las partes que son líquidas, esto es, el agua y el aceite aromático. El agua se puede coger del grifo, pero ojo, el aceite vas a tener que ir a comprártelo. Según donde vayas, seguro que podrás encontrar bastante variedad. Nosotros después de estar un rato seleccionando, al final nos decantamos por un mentolado que una vez puesto en marcha es una pasada. Está construido de manera cuidada, con muy buenas terminaciones, cuando lo coges te das cuenta de que es un producto que tiene calidad y no algo terminado de cualquier manera. Tanto es así que es un aparatejo que no hay que esconder, sino ponerlo a la vista porque lo cierto es que decora bastante, sobretodo por la noche, en que se le pueden encender luces LED decorativas. El funcionamiento es bastante sencillo: - Conectar el aparato a un enchufe - Abrir la parte superior - Echar agua y unas gotas de algún aceite aromático (como digo, el aceite no viene incluido, hay que comprarlo) - Y pulsar el botón de puesta en marcha. Pulsar una sola vez lo pone en marcha de manera continua, mientras que si lo vuelves a pulsar puedes ir seleccionando cuánto tiempo quieres que esté en marcha (temporizador) Además de esto, el aparato es configurable en cuanto a: - Cantidad de vapor a soltar: Que tiene dos posiciones, una suelta más vapor, la otra menos. Nosotros siempre lo ponemos en la de menor flujo, y con eso nos basta. Estoy hablando de un salón de unos 25 metros cuadrados. - Iluminación: Se puede seleccionar que emita una luz decorativa o no lo haga. Si se pone la luz, se puede escoger un color fijo de entre siete disponibles o carrousel de colores. También se puede configurar la intensidad de esta luz (como en el caso del vapor, dos posiciones, que vendría a ser "luz a tope" o "menos luz"). Respecto a los resultados, a nosotros nos parece una pasada. No sólo hace que el ambiente sea más agradable, sino que desodoriza mucho mejor que los ambientadores tradicionales. En un momento tienes la casa perfumada, y además de manera continua. Otras curiosidades de este aparatejo: El vapor no es caliente, sino frío. Tal vez por esto de no tener que calentar el agua, en cuanto lo enchufas empieza a soltar vapor enseguida. Pensaba que le costaría un poco, pero no. No hace apenas ruido (tiene que haber silencio y fijarte mucho para poder escucharlo) y además si llenas a tope el depósito (400ml, esto es, menos de dos vasos) y pones el vapor a "medio gas" (que es como lo tenemos nosotros) te dura todo el día. Una pasada. En fin, supersatisfechos con la compra. Un acierto. Dejo un video donde se ve tanto el contenido de la caja como el modo de ponerlo en funcionamiento. Espero que sirva. En cualquier caso, si alguien tiene alguna duda, encantado de intentar ayudar.

    Love love love this diffuser. Have been wanting to try essential oils for a while after hearing all the rave reviews. This diffuser is perfect to diffuse oils and experience the benefits. This diffuser is nice compact and cute. It has as that glowing ring at the bottom which is a very very nice touch and makes it look premium. The colors can be changed. It appears big in the pictures but it really isnt and would be barely noticable if you wanted to keep it that way. I got the black color and it is superb. Wisper quiet operation. Highly recommend this product.

    So seeing as these diffusers are all the rage I had to try it. So basically they are like pretty humidifiers. It's a nice way to get a light scent of lavender, peppermint, eucalyptus or any other essentials oil in the air. Much prettier than the bulky one everyone's parents would pull out when you were sick. I have been investing in these since moving to the southwest where the humidity is low. My family seems to sleep better with these. You can actually use them with our without the essential oil if you just want to add humidity. The one might be my favorite because of the shape. I don't know why but I makes me think of "I Dream of Genie"

    I love this diffuser! It is simple to use right out of the box. The instructions are very clear and easy to read. I like that there is an auto-shutoff when the water runs out, that way I don't have to constantly check the water level. This diffuser puts out a nice amount of mist, you can see if from across the room. Since the diffuser points straight up, I put a towel under the diffuser so that the table doesn't get wet. This diffuser puts out enough mist that you could use it as a humidifier for a small room. I keep it going constantly in my living room and it has definitely helped with the dry air. I like to use essential oils that smell good so that I get humidity and a nice smelling room at the same time.

    Simple little thing that works like a charm so far. I've run it daily for a week at my desk at work, and it's super quiet, not intrusive, and connects nicely to my computer with the provided usb cord. The cord was a bit stiff to plug in to the humidifier (it's a microusb connection) and because of that I'm going to just leave the cord attached at all times and unplug it from the other end only. I worry that moving the device end of it around will loosen that connection and break it. Besides that, it's about the size of a 16oz coffee cup. Very easy to use and refill. Came with a couple refills for the filter, too, so that's handy.

    As I sit here writing this, I have my diffuser going and I love it. It’s sleek, makes minimal noise except for a little white noise and a little water splashing around on the inside of the machine, but honestly, it just sounds like a fountain anyway, and I like that. The colors are soothing, and it is just a joy to operate. It’s very user friendly and has low and hi mist options, but I can’t really tell the difference between the two. Mist output is great even on lowest setting, for a small bedroom like mine. The tank holds 400ml max, but if I just fill up the accompanying measuring cup once, (about 150ml) I can get about 2-1/2 to 3 hrs of output at the low mist setting. When it runs out of water, the whole mechanism shuts off, lights and all, which I really appreciate because I know some diffusers shut off the water portion when they’re low, but the lights are still on and you have to shut them off yourself~ a pain when you’re snuggled up all cozy in bed or on the couch. Well thought-out design. One thing I am a tiny bit concerned about is I got it in white to match my bedroom decor and it is beautiful, but it is MATTE white plastic, there is no forgiveness here, so you had better make sure your hands are clean, and no essential oils or anything is on them, because it will show up on material such as this. I love the sideways plug, so it sits very ergonomic in your outlet and doesn’t get in the way of other plugs, which is a pet peeve. It cycles thru all the colors in an unobtrusive way, which is what I was looking for~ I’m not a fan of the diffusers where it’s all about the COLORS, I like something a little more refined, and this is it. Hopefully my diffuser and I will have a long, happy life together.

    Se trata de un humidificador, que también funciona como difusor de aromas. Proporciona una relajante brisa de vapor o aroma, y una luz ambiental, para crear una estancia confortable y cálida. Además, está especialmente recomendado por temas de salud, ya que humedece el ambiente reduciendo problemas respiratorios o sequedad ocular, entre otros. Este humidificador tiene una capacidad de 400 ml. Este dispositivo es muy útil y cada vez más necesario en las casas, ya sea porque el clima es seco y se reseca el ambiente, o por las calefacciones. Este producto tiene tres funciones: - Humidificador. A partir de agua que se introduce en el depósito, libera una fina bruma de gotitas, vapor, o una suave brisa fresca, humedeciendo el ambiente. Ayuda a mantener la humedad de las habitaciones, reduciendo el riesgo de enfermedades respiratorias (amigdalitis, resfriados, gripes, sinusitis, bronquitis, etc.), así como sequedad ocular, o sequedad de la piel. - Aromaterapia. Se puede introducir una solución de agua y aceites esenciales, que se desprenden también generando una fina bruma aromática. Es un gusto para nuestro olfato, ya que deja la habitación o estancia con un muy buen olor. Ayuda a proporcionar un ambiente de relajación y bienestar espectacular. También son efectivos en la reducción de enfermedades respiratorias, así como en producir alivio de determinados síntomas. Además, tienen propiedades muy beneficiosas sobre la salud. En primer lugar, tienen propiedades antisépticas, limpian el aire y el ambiente. Por otro lado liberan aromas que ocasionan una respuesta placentera y se usan para modular el estrés, miedo, intranquilidad, ansiedad, etc. Hay aceites de lavanda, limón, mandarina, eucalipto, menta, romero, etc. - Cromoterapia. Incorpora una luz LED, cálida, con dos niveles de intensidad que podemos cambiar pulsando el botón Light. Es totalmente silencioso. Cuenta además con autoapagado, de forma que si detecta que no hay suficiente agua o esencial en el depósito, se apaga solo. Su uso es muy sencillo, tan solo tenemos que girar la base del cuerpo del difusor y se separan ambas piezas. La zona de la base cuenta con un pequeño depósito en el que vienen pintadas las marcas de nivel, indicándonos hasta dónde debemos llenarlo. Una vez hemos introducido el agua o la solución de agua y aceites esenciales, volvemos a cerrar el difusor. Hay que tener cuidado de no volcarlo en este punto, ya que podría salirse el contenido. Funciona en frío, es decir, no se debe calentar el agua ni los aceites esenciales. En cuanto a su diseño, es pequeño, ligero, tiene forma cónica, como con la forma de un huevo, y es color oscuro. Sin duda recomiendo este producto, ya que ayuda a mantener las estancias limpias, con un nivel de humedad adecuado y tiene muy buenas propiedades para nuestra salud. Es muy relajante tanto por la fina brisa que emite, como por el color de la luz. Lo puedes tener en el salón o en la mesilla de noche, y además como componente estético es bonito. No es un gran aparato voluminoso, como otros difusores. Le sacarás partido. Buen producto.

    This is such a handy, nifty little device! I bought it to use in hotel rooms & camping and I couldn't be more pleased. I just received and tried the humidifier.So far so good; I'm impressed with it. For its size it seems to put out a lot of steam. As much as I like the it, I think a couple of things would make the device better: 1)a carrying case or pouch and 2)the packaging I think could be slightly better designed. When I first opened it, I was like, where's the USB cable ? It took me a minute to realize that the items were tucked under the flaps. That might just have been an oversight on my part. For the price, I think it is a great value.All in all, this purchase has made me completely happy. I recommend it. And now I'm buying another one to give as a gift. I love this little humidifier.

    We’ve been using this humidifier for a couple of weeks now. Since we have another brand in our bedroom, we decided to use this one in our car. It was a great decision! We can definitely tell the difference especially since now it’s getting cold in NYC and our car heater is on. Before using this humidifier, the heat from the car would make my sinuses feel dry and I had to immediately open a window. It was a constant struggle between breathing smoothly or being cold. This humidifier makes our car rides much more comfortable!

    Awesome little humidifier. My husband is on the road a lot and he spends a lot of time in hotel rooms. Winter time is the worst because air is so dry and it is hard for him to breath. This humidifier is so small that it fits in his carry on. The mist that it makes is very fine and lasts a long time. It makes nice shhhhh noise that you can hear if it is by your head. If you are like me and hate noise just keep it at the other end of the room and you will be fine. All in all amazing humidifier for people who travel a lot.

    I've had a humidifier in my room for some time now and I've gotten used to it. Considering my commute to work is pretty long nowadays, I thought maybe getting one for my car as well would be a good idea and came across this super compact one and subtle one. Pros: 1) It's super small and light so I keep it on my dashboard with the help of some two-way adhesive, and it's got a fairly sturdy base since it hasn't wobbled off. 2) The mist feature is pretty strong and lasted for at least 3-4 hours or a day of commuting for me. Sometimes it does more but it really depends sometimes. 3) I could barely hear it while driving, so it wasn't distracting while on the road, there's kind of a low hum to it but nothing too bad. Cons: 1) Build quality isn't great although it does stand up to a couple drops on the floor, I wouldn't keep it at a height Overall, I'm quite happy with it and I'd definitely recommend it assuming you prefer using it in a smaller space!

    In this winter weather there are times when my car goes to dry due to the heat & wanted something that would sort out this problem. I was looking for options during when i bumped in to this device. Since it was not too costly i wanted to give it a try. Here is my View of this product after using it for almost 2 Months. Selling Point: ############## As i mentioned in the summary, biggest selling point for me while buying this device is just the cost & the possibility of using it with any micro USB charger. Additional items that gave me confidence to buy this was Amazon's Choice badge & the 10% coupon which was available in the product page to use. Build Quality / Usage: ###################### I'm using this atleast last 2 months and my views are based on my peronal experience with this product Only. * Definately the manufacture have taken serious control over the quality. It works Great... not had any issues * if you decide to use this in your car, then it definately fits in to the coffee cup holder with out any fuss. * it also feels solid & the plastic seems to be of very good quality. * Connectors does not cause any trouble while using from coffee cup holder. * For me the intermediate mode available in this device works well and keep the car cabinet humid enough (avoiding all dryness) * i have tried using it in my office as a space humidifier & it have not caused any trouble * Its runs Quite most of the time. Problem / Concerns: ################### - while using in intermediate mode some time it makes some funny noise.. It will not be heard by others thou. This product makes it a nice addition for using it like a space humidifer (or) a one for car. To be precise, based on my experience so far this is nice product & would definitely recommend to other who seeks my advice.

    Got this yesterday. Please check the pictures. The build quality is good. The amount of water it holds in the water tank is good too. I was expecting a small tank but its decent enough to work for hours. The mist works well too. At home the mist looks small but in car it looks decent. It has 2 modes continuous and intermittent. Intermittent mode throws the mist after 10 seconds for 10 seconds. I wish it has 2 functions 1. To increase the mist spray 2. To add the scented oil. The humidifier has a sticker that says not to add scented oils or perfumes. Overall, a good humidifier for a decent price.

    Works as advertised. Purchased a "personal" sized one because winter is cold and especially dry so I like to keep one next to my bed when I'm sleeping so I don't wake up with dry coughs in the morning. I usually use the intermittent red mist mode so the water supply would last longer. Also, this took me a while to figure out since it wasn't explained in the little instruction manual, but there is already a cotton bar inside the holder, and to open the cotton bar holder you just simply twist and it'll pop off. So in total there are two bars; one replacement and one already inside. I really like how the cable is flat. And in addition, I can recharge my Samsung and LG products with it (micro usb)

     As you can see in the pictures and video, this mini mister does not take up much space at all. That is exactly what we needed. Where we have this mister set up is very small. We could not afford to take up very much space with a large one. Even with its small size it is still putting out a lot of mist, surprisingly a large amount. I hope the video does it justice. Plugging the micro USB cable in provides this mister itspower. That being said, you could run this thing in a lot of different applications if need be. Just for fun I powered it off of a power bank! Even the description shows it being in an automobile cup holder. When not in use we insure it is completely dried out for storage. The cotton rod has held up very well with doing this. Once you run an essential oil through it the cotton rod takes on that aroma. Figure out which essential oil you will be using and stick with it was the best practice for us. If anything ever changes with this mister then I will update this review.

    I was skeptical about this diffuser since I was worried it would be putting hot moisture into the air. In fact, the vapor is quite cool, you can put your hand right over it. It diffuses essential oils or perfume oils well, and has clear instructions for ease of use. Also has a timer and auto-shutoff when the water runs out. The strip toward the bottom turns different colors, which looks pretty in the dark. Design is sleek and attractive. Great product all around.
