Detects four of the most common threats, linked for whole house coverage, easy installation, and no nuisance alarms. What’s not to like?

Nice alarm > Problem mounting plate
Super easy to connect; super annoying to mount. Most alarms either have a hinge and just "click" to the plate or easily twist into a position to flush nicely. My old battery-based alarms mounted/unmounted easily - no issues - none, this thing - what a mess. Out of the package, the method used (a twist on) never crossed my mind for concern; however, the tolerance to twist on is so narrow that it does not easily twist on. I have TWO of these and neither one wants to twist into position. Now I have to find some alternate way of flush mounting this to my ceiling.
