Review: Excellent piece of kit. Just plug and play - Excellent piece of kit. Just plug and play. Still working great on original battery after two years of use. Range is excellent too.
Review: Great and affordable - A simple piece of kit, reasonably priced and looks dead smart. The plug in part is nice and thin so actually was able to be plugged in behind a unit making it invisible but still easily heard. The push doorbell part is smart, fits nicely and the large adhesive pad looks like it will not be moved. Volume control is great, can be heard all over the house quite easily. The only slight niggle is having to wade through the sheer number of chimes to find something which sounds like a doorbell - I mean come on, how many people really need their home doorbell to play happy birthday or an unimaginable number of Christmas tunes! Sometimes it's ok to make things simple!

### ⭐⭐⭐⭐⭐ Excellent piece of kit. Just plug and play

### ⭐⭐⭐⭐⭐ Great and affordable
*by T***Y on 13 April 2024*

### ⭐⭐⭐⭐ Great bell, easy to install, small minor caveat
*by A***A on 20 September 2021*

Great bell , works as expected, easy to install and volume is rather loud; extensive choice of chimes/songs, mainly making the kids laugh (we've put the receivers out of reach 😅 ). Small caveat, the ring around the bell button and the bell icon on the actual button and receivers does not light up (contrary to what the pictures in the description might suggest). I thought the blue circle would be visible in the dark so visitors could find the bell more easily, but that is not the case.
