Rated 3 out of 5 by from Easy to fit Bought 2 of these to replace tired looking smoke alarms, easy to fit. Only downside is screws and plasterboard plugs are not included

Rated 4 out of 5 by from It definitely works! Purchased to replace alarms that were about 20 years old. They are significantly more sensitive and have gone off quite regularly, with burnt toast and bacon and excess steam. I am very pleased with their performance.

Rated 4 out of 5 by from Good buy This is a great value smoke alarm and comes with a backup battery. I found it a little tricky to line up with its base but that might be my peepers these days ;) and it needs a bit of a big hole in the ceiling for the square plug, but that said it's a pretty good buy. Note only 3 stars for performance and reliability because it's still new.

Rated 5 out of 5 by from Replacements Bought as replacents for time expired units backing plate and connectors all the same so it's a shame couldn't buy just the head unit

Rated 5 out of 5 by from What it does on the tin Easy to install, relatively neat, what else can you really say for a smoke head?

Rated 5 out of 5 by from it's a smoke alarm needed to renew/update my electric smoke detectors. easy to fit like for like. only just fitted them so can't comment on it's performance but as I said in my title "it's a smoke alarm" so it's doing what it's supposed to do. test works so i am happy with this product.

Rated 1 out of 5 by from Easy to fit..not! I bought this as a replacement for my old BRD detector because I thought it would be simpler to fit. It wasn't, quality is so poor compared to the old and location of unit onto the base is so fiddly I had a sore neck afterwards! And what's with the piece of flimsy card that turns out to be the gasket, I'd binned this with the packaging and resigned to re-using the old foam gasket until I realised! Very poor, will not buy BRD again and urge you to avoid them too.
