Good easy to read display and reasonable battery life of a few hours. But the main CO2 measurement seem to respond to literally everything, not just CO2 - the readings are very high in comparison with another CO2 detector I have. Also the HCHO and TVOC numbers seem to be derived directly from the 'CO2' readings only, they are not specific at all? So my impression is that it is using one single general air quality detection device, which is sensitive to everything? So the specific readings are inaccurate and not very significant. However having said that, it is a very sensitive device for general air quality and the bar style display at the bottom is a very good general indicator of air quality.. For the low price it's still useful and worth having.

Good device which works well. The only issue with it is the display, the digits are much smaller than the picture illustration, and because it is dim it can only be read in low light conditions.

Seems like a quality product and looks good. It has some great functions too, which seem to work OK. However the display on mine is very dim? I cannot see it in daylight at all and so far I cannot find any way to increase the brightness of the display :-(

Great little device - it's highly convenient and works really well :-) I wish I'd had something like this years ago. I had a little difficulty understanding operation, because the manual does not explain that the 'MODE' button needs to be pressed to confirm changes made from the MENU selections. I figured it out after a few minutes.
