I work in a green house and use this multiple times a day. It works great and is easy to use.

Have had it for a month, simple to use, very fast humidity reading, good design and the color keeps it from getting lost with all my other junk.

no way to offset temperature or humidity reading. The factory calibration was off 6-8 degrees Fahrenheit and 20% RH off compared to 10 other thermohygrometers (all within 2-3% RH and 1-2 degrees) owned by coworkers. when looking for a way to fix this in the manual, I came across a section saying it only works up to 2000m (~6500ft). This was not disclosed in the product listing. This makes the product a waste of money and time when my job sites range from 6800ft to 12000ft in elevation. Would give 0/5 to this POS if I could

No way to check the calibration. The meter displays a temperature and relative humidity, but since there isn't a way to calibrate or zero out the meter, I can't depend on the readings. My fault for purchasing the meter without the calibration function. I'm a home inspector and mold tester and have to know the results are accurate.

It does everything it says and easy and accurate. A great addition to my tool bag. I wish it had a rechargeable battery but no big deal..
