I had one of these 10 year smoke detectors in my home when it died. I simply looked up the same model number in Walmart's website and in a couple of days I had an exact replacement and was even able to untwist the old one from the mounting brackets and twist in the new one. Easy peasy.

PROS: 1. Purchase price of $10 for this long-life no-batteries needed is cheaper than buying batteries for other models. 2. I don't have to change batteries in it. CONS: No directions for activating alarm or for installing it; I had to Google those.

Easy installation %26 peace of mind that we are safe in our home. We needed to replace our old FireAlarm that was 20 yrs old. We kept putting new batteries in our old Alarm. Then I read that the Sensors that detect fire only last 10 years. Now I feel at easy.
