"Not a huge amount to review with a smoke alarm but it works well, looks ok, is nice and small and let's us know when we've burnt the toast! The battery in this one is changeable, unlike the previous alarm i had that was supposed to last ten years and only lasted 4. The test button is big and easy to push and the bottom is flat and wide enough to use some double sided tape to fix to the ceiling."
"Bought to replace an existing smoke alarm. Easy to fit. Not tested under real conditions nor for any length of time (hence an optimistic 5 stars for performance and reliability). However, good value for money as it only cost just a little bit more than a PP9 lithium battery alone."
"Purchased a First Alert Long Life ionisation smoke alarm two years ago (Product code 67523) . The manufacturer guarantees a 10-year working life (including the lithium-ion battery) but the unit failed completely after only two years. The supplier has ignored my many e-mails requesting a replacement under the guarantee. I would NOT RECOMMEND THESE SMOKE ALARMS."
