just a £15 fire angel from b&q
Ditto, just bought one. Claims to run off the one battery for life, which has to be a plus that the temptation to pull the **** battery out to stop it chirping when it runs low is hopefully prevented.
Saw some around the £35 mark, so considerable price differences, I don't know enough about them to comment whether there are different standards of technology though. Price seems to vary according to where/why you buy.
Example in my case, we've bought a new caravan, the old CO detector had flat batteries, a specific caravan supplies shop wanted the £35, B&Q wanted £15. Bit of a no brainer really!
