I whould never buy that again
1. all measurements are higher than my other device show (+200-300 ppm CO2, +10% RH, up to x3 PM2.5). And I have lot of sensors. Outside level of CO2 600 not looks adequate. Hope it have auto calibration and at least CO2 levels will be better with time (first 3-4 days of use - same +180/200)...................................1. wrong measurements (+180/200 CO2, 3x PM2.5, +10RH, +1C t,)2. unable to connect to an app on iPhone, no QR code in device settings3. nothing about connecting app in Device Manual4. GSM/GPRS seems not work for me also (maybe it is locked to US 850/1900 MHz and just not work for European 900/1800)5. install and use Android app is some kind of Chinese puzzle to solve. No application in Play store.6. Celsius not available (no such settings)7. cannot find any options for a firmware update (Firmware 1.0.12)8. the fan inside is loud.9. CO2 level limits are high (it show 1400 ppm as Normal) and limits are not customizable.10. One hour of charging shows 100% (3.7Wh), but real charging continues for at least 1 more hour (up to 5Wh). And 2000 mAh is should be something close to 7.5Wh.11. In operational mode (not Hold) device work about 4 hours on battery (not 60 hours)

So far reading seem really accurate
I usually rarely buy things like this when there are so few reviews, but overall its performed well over the past few weeks. The readings seem accurate, and they come up quickly.I have not benchmarked it, but I compared it to the readings on sparetheair and they were somewhat similar even though the sparetheair site does daily averages.The screen is clear and concise as well.I would definitely recommend it. I will check back in a year if I need to update this review

Defective unit?
The real-time measurements appear to work, but the middle button is unresponsive, so I cannot select anything, or start recording. Must be a defective button :(
