Easy to install
I had to install a couple of these to pass our final inspection and found these units quite easy to install. Given what things are going for these days, they’re a pretty good value for the money.

Useless. Way too quiet.
These would never be heard from another room or another floor. Makes it useless for the garage.

Easy to install but not loud.
These were very easy to install but I am really disappointed with the volume. I installed in in my attached garage over my electric car as a precaution in case of battery fire, but when testing the siren I cannot hear it even on the other side of the interior garage door. Will have to find something that is louder or wifi connected.

Unable to return and it only lasted 30days
It came with two and one started beeping and because my 39 day window to return was one day late I couldn’t return the one beeping! Disappointed

Awful
These have gone off for no reason at least 5 times in the last few weeks. Buyer beware!

Fell off the wall, not very loud.
The sticky tape they use is not good and the detector fell off my garage ceiling after a couple weeks. This made the detector go off constantly which I didn't discover until the morning because the unit is not very loud. It would not have warned me of a fire so it's probably good that I am forced to get another unit.

Not accurate or helpful-malfunctions
I got this item less than 2 years ago and it already chirps randomly-as I'd the battery need to be replaced, but it is a 1 time use battery that cannot be remived/replaced.I found it plenty loud and woke me from sleep on the other side of the house, while it was in installed in the garage. No good reason for it to go off, except it was a cold night.
