    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.

    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".

    I believe this is a good doorbell but it doesn’t meet my needs. However I know not many of these wireless, electronic doorbells can do better. This is not the first I have tried. I live in an apartment with thick concrete walls and I want to be able to hear the ring in my back bedroom. When I am in the living room or kitchen I can hear the doorbell I already have just fine. But when I am in the bedroom working on my computer, I can’t . One reason is the distance and walls, the other is my hearing is somewhat impaired. What I am looking for is an electronic doorbell that I can install the transmitter for on the block wall outside the front door and the receiver in the bedroom and when the button is pressed the ringer in the bedroom sounds with enough volume so that when I am in the living room I can also hear it, even though faintly, given my hearing impairment. When I made my tests before fastening the transmitter to the wall, I thought I had found a doorbell that met my needs. However, after installing the transmitter and plugging the receiver into an outlet in my bedroom, I found that it only worked some of the time. So off the wall the receiver came and my search continues for an exceptional doorbell. Because based on my tests I know that this doorbell can work quite well in a normal situation, especially if the walls are wood or plasterboard, and the fact it did what I want some of the time puts it ahead of most of the others I've tried, I believe it deserves my solid 4-star rating.

    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 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.

    This is a great wireless doorbell! It's nice that there's no batteries required! You can mount the doorbell outside using different methods depending on the surface your putting it on. There's two plug in chimes that you can put anywhere you wish in your home so your sure to hear it from anywhere you are. The chime sounds definitely offer many choices weather you're looking for humorous chimes to classic, it has it all! I was cracking up listening to them all! I highly recommend this doorbell to everyone!

    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.

    These doorbells are so neat, I love that they are wireless, they come with two receivers and one doorbell. So on the back of the doorbell is a strip that you take off to place your doorbell by your door, the tape holds very good and its strong. The receivers I can put in separate rooms so I will be able to hear the bell when it rings, so I have one in my living room and the other upstairs. They work perfectly, I like that I can change the ringtones and you can adjust the volume, the doorbells light up blue also when it is rung. I like to listen and change up the ringtones every few weeks. I get many compliments on the door bell from my company. They all want to know where I got it from.
