So easy to install

Really appreciate a long term battery ( not swapping out battery once a year) and the optional magnet installation is perfect for someone like my mother! Box included everything and very detailed instructions. Unit also is clearly marked on the outside the expiration date.

i just installed these items so it's premature to rate their quality, battery life etc. They do install easy and don't dominate a large wall space. If I'm still around in ten years, I'll let you know about the 10 year batterues and the quality and durability of the product.

Easy to install, works as expected

Really like the mounting accessory that combines double-sticky foam and neodium magnets. this makes it super easy to install, and also to take it down in the future to inspect. no more alignment of tabs and slots and then twisting. just let the Magnets do the work. Otherwise, it's just a normal 10-year battery smoke detector. about 3.5 inches in diameter and off-white color. big button for testing. Loud buzzer when tested.
