    It works well only a few meters away. If the distance is 10-15 meters in my case, it will not be so stable, but it is also sufficient for our small family. After all, the price is quite cheap.

    I had already taken one for my mother, what I had taken was from a single bell, but after I found out that it is really effective I took the one from two. I put one in the bathroom and another in the bedroom, the latter sends the signal to two bells placed in two different rooms while the first sends it to a single bell. You have no idea how necessary these gizmos are, if you have someone who needs help. Through the ringtones you understand which of the two has been used. The thing that pushed me to choose these bells is the fact that they do not use batteries to work and therefore you do not have to worry that they can run out suddenly, also to work just press anywhere on the surface and not just on the button.

    since i put it down, it has never failed me. moreover it is aesthetic and clearly visible. I only put 3 stars due to its fixing system. the doorbell is stuck on a double face screwed to the wall. he did not resist being uprooted by "little jokes". I would have preferred the complete block to be screwed directly to the wall.

    I comment on my experience, shipping very well, received earlier than expected, well packaged and in perfect condition. Contents of the box: 1 wireless doorbell that does not need a battery with a double-sided tape attached, two receivers that connect to any plug, another extra double-sided sticker for the doorbell, two dowels with their corresponding screws in case it is preferred to fix on the wall and an instruction manual that comes in English, French, German, Spanish (not a very good Spanish but understood), Italian and Japanese. The doorbell does not have the holes made for the screws, in one of the photos I have opened the doorbell so that it looks like it is inside, it does not have a specific place to put them, so I guess it can be drilled and put where we best go . Opening it is not difficult, it is under pressure, but it must be done with a little delicacy so as not to break any lashes. Aesthetically in my opinion it is beautiful, both the doorbell and the receivers seem very beautiful and elegant. The operation is correct, the receivers have light and many songs, although it has seemed to me that some are repes. The volume is adequate, has 4 levels to choose from and is perfectly heard. The operation is very simple, in the receivers there are two buttons (can be seen in one of the photos), the button below is to choose the music, and the button above is to choose between the 4 volume levels. In my opinion it is very important to have light when it sounds, it can be very useful for deaf people, with hearing problems or if there is a lot of background noise that does not allow you to hear it well. Good value for money.

    as soon as assembled it works, we are happy, unnecessarily large but pleasant to see; pity only for the deafening, useless and rowdy "melodies" which therefore allow to use only the first available tone. Amazon perfect as always

    This is amazing! We use it in our restaurant. We have a quick service, self serve space, and sometimes the guest needs to speak With the door bell, the guest pushes the button and it chimes in the back of the kitchen. It is loud enough to hear over all the kitchen noise, but not obnoxious at all. I love this thing! It has been so great! The guests love using it too!

    I received this for free to evaluate and provide an unbiased review. I received the doorbell with two receivers. It works very well and is easy to use. The second it comes out of the box, it is pretty much set up. All you have to do is decide where you want to plug in the receivers. There isn't much to say other than this is pretty much perfect. It is important to note that I haven't tested how durable it is, so I can't attest to it's waterproof claim and how well it will last outdoors for prolonged amounts of time. I assume that, since it's a doorbell, it was made to withstand the outdoor elements. Pros: -Very easy to use -Has many different doorbell sound options and you can adjust the volume. -The doorbell has a sticky surface on the back so you can stick it on just about any surface, but if that isn't an option, they also give you all the pieces needed to screw the doorbell onto a surface. -As far as I could tell, it doesn't need a battery and works out of the box. Cons: -The package claims the item is "ultra thin," but its about as thick as a hockey puck. -The sound quality is like that of an 8-bit system in my opinion, but that seems about normal for a doorbell that doesn't use the standard doorbell chime. If you want a doorbell with receivers to place wherever you want in the house (wherever there is an outlet), this product will pretty much give you all that you need.

    As long as they hold up over time I will be thrilled with the purchase. I had a hard wired doorbell that was literally a bell, and jarred me every time it rang. And then the wiring went haywire, and the bell stopped working. Well I wasn't going to call an electrician for that. So I took a chance on this wireless set, and they're doing well. As for changing the tone, I like the sound that was preset better than the other sounds, but it's nice to have a choice. Also, being able to adjust the volume is a great feature. My place is relatively small, so I have it set low. I placed one near the front door, and the other in my bedroom. I never miss the sound. Thanks

    I've been looking for a remote doorbell replacement, but the problem is that most all of them rely on a battery on the door transmitter, and when that battery starts to go, the sound box usually goes nuts. So when I saw this device was a batteryless solution I thought I'd give it a try. WOW, it actually works. I was really doubtful that a single click would provide enough kinetic energy to power a signal strong enough to send to the chime box receiver unless they were located very close, but I've tried plugging in the chime receiver all around the house, and it works! U've also had no problems with "false" chimes from local RF noise, etc. Overall a very impressive little device.The box comes with an attached adhesive backing, but also contains screw mounting, and an extra adhesive pad for the transmitter. I was able to use the attached adhesive backing with no additional installation requirements. My only concern is that because it's essentially a big white round button, that people may not realize that it's a doorbell, vs. confusing it for a speaker or something else. I'm sure it needs to be large to capture enough kinetic energy to transmit its signal. I like the look of it, so I'll just have to wait to see if people "get it". EDIT: After several deliveries, they all seem to "get" that it's a doorbell so worries alieved.

    These are great, so many sounds to choose from. They are loud and the fact that there are 2 makes it even better. That led is helpful too, specially during the night. I can move them around if I need to, just plug in and ready to go, specially while will ring in the garage.
