Small But Very Loud,
This review is from: Kidde I9040UKB Lifesaver Smoke Alarm with Micro Test Hush Function (DIY & Tools)
I purchased 2 of these when they were on offer (thank you HotUK) I was surprised how small they were compared to the ones I was replacing but then I was surprised how loud they were when I pressed the test button.
Very good item and being smaller than a standard smoke alarm they are less intrusive.
I can't remember exactly how much I paid for them but I know it was less than the price of 2 new PP3 batteries and they came with the batteries so it was a bargain!
