Velcro doesn't stick very well
My only comment that precludes a 5 star rating is that the velcro doesn't stick to plush linings inside my guitar cases. Three different cases, same result. I opened up one case to find the unit had fallen away and was sticking to the finish on my $4K Martin. Tense moment! So now it's down to using the metal clips provided. The size of the clips limits where the units can be placed in the case, which could affect accurate readings.
Better than most
This hydrometer is much better than their previous ones. I place it (previously calibrated) in a Boveda calibration pack along with my D'Addario Bluetooth hydrometer. Leave it there for 12 hours and note the difference in the D'Addario ap "Guitar Name" ie: -2 HD 28. This remains calibrated till there is a big temperature change then it does need to be recalibrated. If you only use this hydrometer, place it where you can quickly look at it as the RH quickly changes when the guitar case opens.
