Review on 🚨 HECOPRO Digital Display Carbon Monoxide Detector: UL2034 Compliant, Alarm Clock Warning by Damon Mertz

My old CO2 monitor has reached the end of its life. I needed a new CO2 monitor and needed it fast. I've searched both eBay and Revain and this was one of the most economical CO2 monitors I could find. Not only that, it was available for next day delivery. I received it today, just charged it with 3 AA batteries and hung it on the wall. It works great and actually has a brighter and nicer display than my old one which cost twice as much. Best Overall Value, Fast Free Shipping, Easy Installation. 100% satisfied!
