    Loving this product because I assign this outside wireless for my package that come to my place. I place it on my fence because I have 2 dogs that the mailman can't pass the other doorbell near my front door. I have that issue lately of the mailman don't leave the package inside the fence because my labrador start distroying my package box. So I did some thinking of getting a second doorbell that for mailman to press, and it works like a charm and sense then i know i have a package outside because I also put a name to the doorbell. As I took a picture of that doorbell pretty cool idea of mine just for the mailman to buzz that doorbell outside my fence. Price affordable and you don't need to replace battery anymore, because the other reciever plug to the power.

    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.

    Remarkable device! This doorbell not only appears to be very expensive, as it's actually quite elegant and inconspicuous in design, but it also performs melodically, and magically. The ability to customize the chimes and volume tones, as well locations about the home, has made it an artful and highly functional addition to our in-home office and garage door entrance. Additionally, it's the perfect solution for announcing arrivals at our two 'other' entrances. Since most people visiting never use our front door (which happens to be the only one with a wired doorbell), we have found this wireless doorbell solidly serves to address the problem, with a touch of class. As such, we have ordered two more. It's simply a marvel!.

    Grabbed it on a deal. Didn't believe the outside door/button (you just peal & stick) needs NO BATTERY! (had to get a new similar door bell when the old battery operated outside button finally fell off & was shattered. For the price ... Amazing.
