Great product
I was skeptical about these because they were kinda cheap and well I just needed them in a pitch. But hey they are awsome.They give my family a peace of mind, batter life has been amazing so far and the sound level is perfect for our big home.These were also super easy to mount and came with all the hardware to do so, so that's a major plus. Highly recommend these

Alarm is very loud
It is Made well. I like that it shows the digital numbers if there is a carbon monoxide leak. Battery operated. The price is very reasonable for four alarms.

Works for a while
Worked for a while but failed before any battery change. Kept beeping even with new batteries. Had to thrash it.Update on my review. The seller replied to my review and offered to send me a replacement free of charge. He mentioned that the original item may have been able to do a reset although I had already discarded it. The seller then sent me a email that a replacement was on its way.Great customer service support!

A Breeze To Set Up and Prepare
Hello All,The OLUNCLE Two-In-One Smoke and Carbon Monoxide Detector is a breeze to set up in an effortless plug-and-play straight out of the retail box. It comes with 2 AA generic batteries to install on the rear backing of the unit. Although, there isn't a direct battery cover hatch like with most electronics for some reason or another. The circular ceiling rear mounting plate nonetheless doubles to cover over the exposed set of AA batteries all the same.I chose not to mount to the ceiling my smoke / monoxide detector and kept it on top of my refrigerator in a basket instead. The unit is quite compact and weighs a few ounces with a shrieking TEST button on the front face plate with an electronic LED display. Be sure to be a few feet away or turn the unit away from you when you press the TEST button, it's that extremely loud.The unit comes with a set of aluminum small screws with a set of plastic mounts for the screws. The instructions are only in English with a legible font size overall.

Do not buy if you want to be safe.
My family and I have been unsafe for more than a year with this product. I would randomly press the button to make sure they work and it would beep as though everything is fine. I left a pot on the stove and the kitchen was full of smoke and the alarms did not go off. DO NOT BUY THIS PRODUCT IM WARNING YOU.
