Rated 3 out of 5 by from Wrong colour I needed to replace an existing alarm which is why I bought this particular item but as others have mentioned it is grey and wouldn't buy again for that reason.

Rated 4 out of 5 by from Does what you need! Got a few of these to fit in replacement of existing ones that had come to end of their life, easy to fit, battery compartment screw is a bit fiddly and they aren't really sturdy compared to aico smoke alarms but they are half the price and do the same job!!
