Easy to set up and works immediately. I'll probably purchase more of these for the rest of my house.

May 30, 2021Simple peace-of-mind
I purchased this for my laundry room which sits right below the gas furnace in the attic. It gives me some peace of mind to know that this will detect any CO leaks. Easy to setup and hassle-free due to the 10-year sealed battery. Pro-tip: wear earplugs when testing the alarm. It is LOUD!

Not requiring external power is a big plus. That makes it easy to place it in an optimal location.

The product came in a reasonable time. Easy to install. It hasn't alarmed yet, so that is a good thing, I think. I have another alarm and it hasn't gone off either, so I believe this new one is working as it should.

Arrived promptly. Was looking for an alarm to use in new room. Easy to mount on wall. This unit should last 10 years.

November 18, 2018Carbon Monoxide Detector
I purchase two MC304SB stand alone carbon monoxide detectors. Installation and testing was easy. Now I need to order 2 more that I shall tie into my security system. Great product, reasonable price, and good installation instructions.

June 23, 2016Met all my needs when it was most needed.
We purchased over 115 CO Alarms to meet a new mandate by New York State. The pricing and quality of the alarms, plus the excellent service provided by Universal Security Instruments made this a no-brainer. I highly recommend.
