Super and cool-looking

It intrigues anyone who sees it, and they're instantly curious about what those numbers mean. I have other CO2 sensors and it agrees well. My only (minor) issue is that I wish you could change settings (C-to-F) during the calibration period, so you can turn it on and leave. Love the battery so you can move it about without powering off.

nice device

The device works fine and the response time looks reasonable.

CO2 meter

So far so good.
I have a Mac, so haven't yet been able to try out the data logger capability, if you have info on how I might do this with a MAC, that'd be great! THANKS

Handy unit

Works well. Very enlightening. Especially interesting to measure levels in a small car. Can be quit high. Lecture rooms as well. Much easier to understand drowziness during lectures. Thank you

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
