Review on 🌡️ Temtop M2000 2nd Gen Temperature Monitor by Shalom Germann

Update: 10/11/2018 After Temtop contacted me about the issue, they sent me a working air quality monitor. The block works perfectly. I am very happy that the problem has been solved and I can now check the CO2 in my house. Excellent customer service and quick response. I uploaded a new video for reference about the CO2 monitor part. Original post: 08/28/2018 This is a great device though; it has some quality control issues. I have had the device for several months. I checked the accuracy values of PM2.5/PM10 and HCHO which turned out to be accurate. The problem I had was that the C02 readings never worked. I let it calibrate for 30 minutes outside, 3 hours outside, 30 minutes inside and 3 hours inside. It never worked. So I'm deducting 2 stars as C02 levels are very important in determining indoor air quality. I really like the design of the unit. The internal components are made of plastic, while the external components are made of grippy rubber. The device has a USB port for charging. The software has an easy to use navigation menu that is responsive. Graphs provide real-time readings and show air quality levels. Overall, this is a great air quality monitor with some minor quality control issues.
