Poor quality
The item costs its money, but it needs something to improve in terms of quality: you will be required to adjust it using some other measurement tools that sounds very strange as it needs to be done during the manufacturing process.

It does the job so far.
I wanted a small hydrometer, to install it inside my classical guitar's hard case, in order to monitor the humidity. I compared it with another one (digital one) that I have in my stoudio and it's quite accurate. Four stars because ok it does the job, but it's not the best hydrometer out there : )

Needed Calibration
I had to calibrate both the temperature and the humidity scales. After that it works ok
