Easy to install Bought this alarm as I managed to break the previous one. Fitted right into place with no fuss. Luckily, I haven't had it go off but I'm happy it's there.

Was an easy replacement for existing Kidde units Fitted batteries did not last more than 12 hours. Low battery beeps started in the middle of the night. Safelincs refunded the P&P without any hassle, as I had already bought new batteries.
