Thank you for this product! Once I found this, it is the only one our Fire Department gives out! It has all the elements that are needed for a competent customer use: digital, 10 year sealed battery, disarm key, not a plug in, versatile to be hung at eye-level. All these features are important to fight this world-wide battle against CO poisoning. Only negative? I wish it was advertised and easier to purchase. Thank you for all you do.

Excellent quality product
Previously we've used other brands of plug-in CO detectors found at the big box stores -- useless during an electric outage and they failed before the warranty ended. We searched and found USI products. These USI CO Smart Alarms are well made and great value. Love they have a 10 year sealed battery, and can be used tabletop or easily wall mounted. Just added two more to our home. So easy to order, and fast shipping from USI. These last, are well made and give us peace of mind - thank you!!

10 year sealed co monitor
Have used Universal Security CO monitors for years. Decided to try 10 year battery monitor instead of changing batteries every year - after using their 10 year smoke detectors for the past 2 years. Great products..
