Good sensor doorbell
Took a little while to set up to the ringtone that we wanted, as there are so many to choose from, but itâs a fantastic bit of kit for the money!The sensors are easy to fit, and the noise level can be adjusted – it goes very loud!

Door chime.
Works well and easy enough to set up. Not keen on the fact that that it chimes when the door closes as well as when it opens.

3 Stars
It occasionally stops working, but overall itâs held up better than others Iâve tried. Iâd give it 3 stars mainly because itâs the only one that hasnât completely failed after a few months
