Tronic Grocer Digital Cigar Humidor Hygrometer Thermometer 1 3/4" Inch Round Black Face 001-c

It works great. Very very useful. I bought a new battery at walgreens. Problem solve

It's cheap and the digital readout was illegible. I'm not even bothering to spend my time returning it.

so far not impressed. Just received this hygrometer a bit earlier than expected but, the button to change from C to F is non-existent, you can see the circuit board through the little hole that should have a button. Celsius means nothing to me.

A+++, came as ordered, will use again

seems accurate

Not as accurate as I would like

Simple and effective

Worked great in my observation bee hive!
