Review on 🌡️ GZAIR Temperature Relative Mountable 0-5000ppm Test, Measure & Inspect: A Comprehensive Solution by Michael Boyce

I'm trying to write an honest review here - I bought it to measure air pollutants and it turned up in a search - it doesn't measure air pollutants other than carbon dioxide, it measures that and humidity, and for those things it seems very accurate (I've compared it to other, more detailed units). The reason I'm giving four stars instead of five isn't because I was misinformed, it's because the UI is very crowded and the top left chart with squares looks like something from the 80's, could be better
