I just received my product and I’ve been using it everywhere I’ve been. Waiting for when I go onto an airplane and check it out then.

Still prefer the QP Air Monitor Lite from you


After more than a year of purchasing and comparing 5 CO2 monitors (including 1 junk monitor from ebay), I regret to report that I am disappointed in the new CO2 monitor. The screen is quite hard to see across a room in daylight, and the placement of the green/yellow/red indicators is not great. The temp/humidity readings are in really small font and not legible at distance. I also did not find my unit as accurate as I would have expected (comparing to Aranet4, CO2 Click, & QP Lite, all had for more than a year, all calibrated; Click not pictured). I think the Aranet runs perhaps 50ppm high, and the CO2 Monitor tended to be 70 to 100 below its measure for the two days I tracked it. It definitely had to be calibrated upon first use.

Yes, I love the battery life! But that's the only real plus side for me -- for less than an additional $30, I will keep and prioritize the QP Air Monitor Lite that you also offer. Its bright screen and sufficiently accurate PM sensors are real benefits (as are easy-to-see temp/humidity readings on rotation). If you could just extend the Lite's battery life, you'd have the piece de resistance in my book!!
