Review on 🌡️ Accurate 99% Precise Humidity Temperature Detector: Ideal for Optimal Conditions by Andre Bennett

This unit has very high CO2 levels that you should see from any small space. If you can see well, a large room. Temperature and humidity readings are smaller, but still higher than many devices. This unit is larger than any of the 10 or so other air monitors I own. So if you want something compact, look elsewhere. Perhaps most importantly, the unit I received turned out to be defective. It turns itself off after a period of time regardless of how it is powered. I tried 3 type A batteries, the included 18650 battery, and powered it via the USB-C upstream port. In some cases it turns off in less than a minute, like just now. I haven't even done an accuracy comparison test yet, but while it's accurate for a short time, it has one big problem.
