So easy to install. I did this while working in the office. We needed this as working in the back office cannot always hear customers coming into the shop. So many different music modes and volume adjustment is great.

Nice wireless doorbell. Lots of chimes to choose from. No issues so far.

Brought this for my father in law so that he knew when someone was opening his door. Works really well too. It was easy enough to fit. The only issue I had was that he has a upvc door that sits proud of the frame. I solved the problem with a spacer to bring the sensor and magnet back in line with each other so that it could work efficiently. And it does.

Worked for a few days then stopped working. Had to return this and buy another one.

I brought this fabulous alarm and put it on my garden gate it's loud enough to hear any where in the house easily to install

Bought thus fir my daughters shop. Very easy to fit with the sticky back for the sensor and the plug in receiver which has a ton of different tunes that you can pick from.

Advertised as 120db loud, not remotely close. Old doorbell was much louder.Getting the push apart to access the battery is fraught with disaster, likely to break. When battery fails, I'm likely to get a replacement, ot one of these though
