Bests & Worsts Reviews from Amazon

Smaller than a typical smoke detector, which I didn’t expect (it’s probably in the description but I missed it) but so easy to install. I used 3M command strips to hang them like I saw suggested in someone else’s review so I didn’t even need a screwdriver. They’re light enough the command strips are plenty to keep them mounted. Took me 2 minutes from opening the box to done. Would definitely buy again and recommend to anyone.
