    • Smoke detector
Size: 8 Packs
Easy to mount with two options using screws with wall anchors or adhesive surface and magnet on each detector unit.

    • Great
It works like it's suppose too. Smaller than what I thought it would be but very loud. It does come with a self adhesive circle so you can either stick it to the wall or it does come with screws also if needed to screw it onto something. Works great for the price. Will order more.

    • Decent smoke detectors, but plan to buy some batteries
Size: 4 Packs
I bought these a few months back and they were easy to install with the adhesive backing. One small negative is that the batteries that come with them don't last long (mine started going about 2-3 months in), but I purchased high quality lithium batteries which should hopefully fix that issue.

    • GO OFF FOR NO REASON AND FREQUENTLY!!!
Size: 4 Packs
DO NOT WORK!!! They keep going off with no actual cause and then I can't get them to stay off. Wish I could return these, but now it is too late. I will have to purchase something else. Loud, but defective. Not sure if it is a battery problem or what is causing the issue?!
