    Great guarantee from factory

    My home builder installed these types of detectors when he built the house 8 years ago. I've had several go bad or simply reach the end of their service life according to the "chirp code" and the company replaced them free without any argument or even proof that I bought or owned them. The original detectors were guaranteed for 7 years, I think, and now the warrantee has expired on all of them. I bought this one as a standby replacement when another one goes on the fritz in the future. These are the exact same model and the new unit plugs into the existing base and turns in without having to replace the old base which makes replacement easier. Other than having to replace a few of these under warrantee, I think they have worked well and recommend them as a good detector.

    Replaced a similar First Alert Combination Alarm

    Using it to replace a similar item that failed. I can't evaluate it by the star system. When reattached to the the wall connection and pressing the test button everything checked out. So it works as it should. If it continues to work for seven plus years I'll be happy.

    Absolutely love these things. Kills two birds with one stone per say!

    These units are obviously great quality as expected from BRK & First Alert. Having hardwired units is the only way to go. These have the combo Smoke & o2 sensor/alarms. They come with a dust cover/bonnet as you will see in my first picture. Great for when doing any remodeling. Keeps dust out so as not to damage the sensors. I even recommend holding on to these in case you need them after initial install! Easy as pie to install and so far have operated flawless. I highly recommend these units and purchasing them in a multi-pack here rather than in store. Way cheaper this way. Great Quality, Great Value. They are a must in our house for safeguarding my family for sure!
