Very good for the money it's a lifesaver...
It was great, a like for like swap with one I installed 6 years ago, the one I bought was the updated version and was a straight swap with the same wiring connections although I didn't need to swap the back plate I still did as the old one was yellowing and would off looked odd. It also comes with a Duracell battery so a good quality.

Fit existing ceiling plate for older model being replaced.
Bought to replace same make of ageing ones. Brilliant as even though the newer detection type they fitted existing ceiling mounted plate and electrical connector, so did not need electrician so that saved a few pennies. Been up a couple of weeks so far and seem fine. Tested them all once up using test button and alarm functions just fine, plenty loud enough!
