『No Battery Required』Wireless Doorbell Waterproof, AURTEC Door Chime Kit with 2 Plug-in LED Flash Receivers & 1 Press Self-Powered Transmitter, 51 Chimes, 4 Volume Levels, No Battery Required, Black

Great door bells, so easy to install with a choice of alert sounds, great for me being hearing impaired, just plug into an area that you can see when the bell is ringing as the light flashes, it is so easy to move the plug to another room if watching television, or reading. My family are delighted that finally I know when someone is at the door.

So easy to set up no wires no batteries to worry about. Excellent product

This is great. One upstairs and one downstairs. Variable golden setting and numerous chimes to choose from. Small, compact, no batteries to worry about.

Looks far more expensive than it was. Easy to install and no problem whatsoever. I just hope it lasts a long time... Fitted both front and back door. Many tunes to choose from. All in all a lovely item.

What a great idea. Works with no battery required and gives a good loud ring. A good buy!

The bell sometimes rings on its own...But its ok Regards

Seriously good doorbell at a low price. The battery-free bell push works brilliantly and the remote ringers operate first time even in a large house. The bell push design is also elegant and fits in well with traditional door designs.

I really like this doorbell. It was easy to install no wires. You have two sticky pads that come with the doorbell and the receiver. Place receiver into the electric socket and pair the two devices There are 51 musical themes you can choose from I choose Ding Dong. It's entirely up to you what musical theme you want. Place the sticky pads on the back of the doorbell adhere to your front door pillar. Although be careful you don't put it upside down like my sister did and I had to re- install. The doorbell is wonderful for its price no more missing the postman or courier.
