Great small lightweight smoke alarm
Haven’t had any issues yet, nice because they have a drill feature but are also very light so you can stick them to things easily.

Great product and great price
I needed a couple of these for a rental house that uses natural gas and it doubles as a smoke detector. I actually purchased another one for our home. They are very inexpensive and you don’t have to worry about any unknown gas leaks. I’m happy with it

Great Product!
I bought this alarm to take when I travel. I have one in my house. I know this brand is very reliable. I tested the alarm, it has perfect noise range! I’m taking this alarm when I travel makes me and my family feel safe. The alarm is very functional and has a long battery life! I gifted one to my sister as she travels as well.

It's your home and family safety device
Pack of 2, both malfunctioned, first one from the instant I put batteries in, alarm kept going off. The 2nd appeared to work properly for 5 hours, then it woke the children, had to eventually remove batteries to stop the alarm. Here's a tip every 3 to four minutes the green led light would flash. It lit up our hallway. Grateful for only having to holes for mounting the one. Funny how when replacing something that needs to be mounted it always requires new holes to be drilled. I was foolish skimping on cost for for a smoke\ monoxide detector.

Battery connections
The battery connections are poorly designed, sometimes they will not connect even though the battery is fully seated and are difficult to remove for replacement, this defect could lead someone to think it is operating when it is not, be certain to check each time you change batteries.

Cheap and good
Is very cheap and good. It is cheap price not quality. Uses 2AA batteries so you don’t have to hardwired in. Would recommend.
