Customer Reviews
★★★★☆
It's a very good product and I would recommend it. However I was disappointed to realize the battery autonomy is less than 24 hours.

Great for monitoring air quality in my home, and love the CSV exports and API access.

★★★★☆
I check it every day and compare (for CO2) the variations from one moment to the next. When it's too high, I bring in fresher air and the results are immediate.

★★★★★
Fairly simple to setup. Compact but easy to read at a glance. Light and easy to carry around. Seems very accurate so far. I use it plugged in most of the time, but seems to have a decent battery life from what I have seen so far.
