Beautiful and convenient hygrometer. Easy-to-read screen (without backlight) and min-max function for those interested.

The measurements are relatively accurate in temperature (e.g. +- 0.5°C), while in humidity it has a small error downwards of about 5%. That means I always add 5% to what it shows and I'm fine (this is confirmed after testing with a more expensive hygrometer).

Finally, the battery lasts easily for 6 to 12 months, I don't remember exactly because I rarely have to change it.

The build quality is quite good for its price, I have had it for 3 years already and it looks like new.

Bonus: it also shows the time, which is convenient many times.
