This 2 pack works great. Arrived on time, well packaged, same as in Home Depot and Menard's, but less expensive. by at least 10%. Installation was easy with no problems. I would definitely purchase from Amazon again vs. my local stores.

The smoke detectors were as described. They were easy to install. They were shipped in a bag and not in a box. The smoke detectors came out of their box but looked fine when I inspected them. They should have been shipped in a box and not a bag.

You gotta replace your alarms after 7 years or they may not work so here I go. Bought these babies to replace the same brand. Easy switch out, sleep well again.

Surprisingly, both packages (I had 2 orders) came without screws to mount it. Interconnectivity is a great feature!

Easy to install (wiring is not compatible with older models, but easy to swap), work in network. The only problem is lack of voice announcement for different threat types.

Previous home owners installed cheap smoke detectors in the kitchen area which would constantly trigger when I was cooking. Swapped over to these and no more false alarms. They're very loud and have different tones for fire and CO. Easy to rewire and mount and was even able to add to home assistant with an external module

I replaced our old Kidde combination detector with this one. The old one went off in the middle of the night (as per usual for these things) and I tried to clean it by blowing it out with a hair dryer but no dice. This one has a slightly different plug connector than the old one, and I needed an adapter which I found at Home Depot.
