They work as advertised
You have to burn or oxidize the sensor in before it will work properly. Which means powering it for about 8 hours and letting it settle for an hour before getting accurate readings from it.

It is a decent sensor, well made
Does the job quit well. On-board pot is very useful to have.

not very accurate
These are so cheap, thought I could build an alternative to an expensive air quality meter. I burned in all of them for 2 weeks, the numbers fluctuated so much and were never close to reliable, not really worth it for sensing CO2 at least, I wasn't interested in the other gas concentrations.

Worked as expected, make sure you use the right library
Never was sure if I've used it correctly because of the burn-in procedure, but there is a proper way to 'calibrate' the sensor. Make sure the calibration is done correctly or your readings will be significantly off.Taking off a star because of no instructions on calibration or code provided, but these can be found on Google with a bit of research.
