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

Easy to install, just fixed button to door frame with the adhesive pads, and plugged the unit into the wall socked. Worked straight away with no need for additional pairing. Happy with the simple chime, but all the others are tacky. Overall, very pleased

I was surprised to know that there are doorbells that were self powered. It a great alternative or even an improvement from the traditional electric doorbells. It still needs the receiver connected to the power. You can also adjust the volume, set different bells and also receiver light. Installation is easy, you just have to stick them with the double sided tape provided. the quality is top notch and size is right were you would want/ expect. Only down side is that the reciever light won't turn off even if you want them. But it's even mentioned in the product description

Great doorbell with lots of sounds to choose from. Volume is controllable and they have a blue light which is light sensitive.

Brilliant, exactly as described. Simply attached the press button to the door and plugged in the receiver/chime and away we went. Will mess around for a bit until we make a more permanent decision on which chime we will use on a regular basis, but easy to change using the button the receiver.

Very dependable, I have been pleased with this. It works well .

Value for money also saves having to look for batteries

The doorbell works fine. Just what I wanted.

Straight forward to install, value for money. Very pleased & hope it weathers well

Excellent product
