FUNEW Cigar Hygrometer，Round Analog Hygrometer for Cigar Humidor，Cigar Box/Cigar Cabinet 2inch Diameter Silver

Love the analog look, pulse I’ll never have to worry about batteries. Reads exactly correct.

Biggest piece of garbage. Wouldn’t calibrate. The Velcro pulled off. The calibration screw had some obstruction in the slot. I just threw it away.

Well short of the 2" you have listed. Thanks for the headache

Two laid side by side had different reading...I returned them

Bought two hygrometers. Calibrated both against Boveda packs at a known humidity levels. One hygrometer needle moves matching Boveda humidity level...but only after calibration (turning dial to match first humidity reading - poor manufacturer calibration). The second hygrometer needle doesn’t move as much (as if it doesn’t have full range of motion), is very slow to respond, and not accurate despite numerous attempts to calibrate - calibrated at one specific humidity level (eg 49%), then measured against a different level (eg 69%) - also tried calibrating high and measured low - still poor accuracy. While inexpensive, it is still too costly as it does not function. One works, one doesn’t....hence 3 stars (should be 0.5 star lower).

I purchased two units both are off by 10% not a huge issue now that I know, calibration is not possible. If you have ocd don't buy this unit. Also all of the openings are on the back making the Velcro option not viable
