  • Good product
Style: Standalone Model (1-Pack)
This smoke detector gives me peace of mind. It was extremely easy to install — just mount it and it’s ready to go. The battery is long-lasting, and the test button works perfectly. It looks sleek and modern, and it’s super sensitive (without being annoying). Great investment for home safety!

  • Great for kitchen - no false alarms
Style: Standalone Model (1-Pack)
Wife is a professional chef. Some entrees are cooked FAST at high heat - and always perfectly. However, a traditional ionization smoke detector was false-alarming frequently as she was finishing her cooking. It was joke-worthy a couple times but that gets old really quickly. So we replaced the "nuclear" smoke detector with this one and it's great! No false alarms for fried eggs or shrimp scampi! Easy to install and fit perfectly where the previous one was. ... show more

  • Works well and looks great

  • Solid, but double check your mounting situation!
Style: Standalone Model (1-Pack)
Seems like a good quality smoke detector, but be aware that the provided mounting plate doesn't have holes for a standard electrical box. I previously had a hardwired detector, ordered this thinking I'd just skip the hardwire and screw the mounting plate into the box. Holes in the mounting plate don't match up, so I had to measure and drill new ones to mount it. Annoying extra step, but other than that it's fine. ... show more

  • Works great!
Style: Standalone Model (1-Pack)
So far so good. Hung it near the garage and it worked when I tested it. Cheaper than my local store and not too big for where I hung it up. May buy a few more as spares bc sometimes ours work for a few years and then they quit. Yes, changing the batteries helps which I do every time change we have, like spring forward, fall back with the clocks times... Only because it reminds me to do it even if the batteries aren't dead, I do it anyways. Just word of thought for all you Amazon people out there. Be safe NOT sorry. Quick Shipping! ... show more

Style: Standalone Model (5-Pack)
Easy to install but not smaller than a standard smoke detector. Had to screw into the sheetrock instead of the plastic smoke detector holder in ceiling.
