Innoo Tech No Battery Required Wireless Doorbells, Weatherproof Door Chime with 2 Receivers, 500 Feet Electric Doorbell, White

This doorbell is fantastic in many aspects.The system is very easy to set up, in fact, there is no setting up really. You just plug the bell sounder into a socket, stick the bell push on your door and it's done. Push the battery-less bell push and the first chime sounds. All you need do now is to set the volume on each receiver and choose one of the 51 chimes. Some of them are quite long! The units look OK, the range is good and it works.Receivers are very small and lightweight so can easily be pluged in narrow spaces and even when pluging them on the wall, socket can hold them easily.

Seriously impressed!! Battery-free is the biggest plus point as they’ll never run out of battery without you knowing! They were very easy to set up. The connection between the button and plug-ins is reliable. The LED lights work very well.We have a large house so the extra plug-in door bell is very useful for upstairs. The transmitter to receiver range is excellent - no problem with reaching from front to back of a large house. I highly recommend the product for both it's simplicity to install and it's functionality.

This is one of the best items I ever ordered.This wireless doorbell does not have a single battery inside. Thus, it relies at the push of the button in order to generate enough electricity to transmit a signal to the receiver. One would automatically presume that that push must be very vigorous. Amazingly enough, a very gentle push on the button works every time.

I've had these for a few weeks and I've been happy with them.The technology fascinates me, I had no idea it was possible. No more buying those expensive annoying little batteries for the doorbell button.They have a really good range and the volume adjustment is useful. Have one receiver upstairs and one receiver downstairs and have had no issues at all.

So easy to set up. I went for this model because no batteries required. Self powered button and plugin ringers. 2 minutes after the box arrived, it was already working on it’s place faultlessly. No wiring, no batteries. Plug and play. Two receivers, so you can use them in different parts of the house. Overall a very good product - I have already purchased a second set for a side door.

This doorbell works very well. The chime units are on the second and third floors, and we do not have an issue with the range. Installation could not be simpler: plug in each chime unit, and stick the button at your door.

It works great. Experimented from a distance of 30 meters. It works great, is characterized by the presence of several beautiful tones.Recommended.

I really really like this set! I’ve been so frustrated in my last couple of houses where I either didn’t have a doorbell, or the original didn’t work.I tried some other battery sets only to find the battery would go out after just a couple of weeks (with very little use). I busted one trying to change a battery. Another one just plain quit working, even with a fresh battery.I work from home but my office is on the opposite side of the house from the front door. I got sick of missing visitors or deliveries. I’m so glad I found this doorbell! I literally spent more time picking out my ring tone than I did install them. It works very well, I never missed a visitor again. Highly recommended!
