dodocool Self-powered Battery-free Wireless Doorbell Kit with 1 Battery-free Transmitter Push Button and 1 Plug-in Receiver White

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.

SUPER EBAYER. GREAT ITEM. MANY THANKS. AAAAA+++++++

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.

Get it installed and ready to use literally in 1 min. Great product!
