The Hygrometer works well..It came with instructions to calibrate it to 100%..It was off by about 20% before calibration, so be sure to calibrate it..I also did a 75% calibration just to see if it agreed with the 100% calibration..It didn't...With the !00% cal set , the 75% cal was at 69%.. So i just split the difference and set it at 72%.. It seems to agree with the electronic hygrometer on my dehumidifier so I believe it is a pretty good meter for the money..

Cheap plastic and needed calibrating when it arrived BUT it has worked well so no complaints there. The only real knock against this hygrometer is the domed face makes it difficult to read with glare from lights but for the price I cannot complain.

I use these in my guitar cases. I have paid 30.00 each for digital type hygrometers. I took a chance on these as they had a calibration screw on the back and they were small enough to fit in my guitar cases. After receiving them I checked them using the salt and baggie method and them calibrated them. At this time they seem to be working fine and they are more accurate then any of the digital models I have. I am keeping the humidity correct on some expensive guitars (Martins). For the price you can't beat these little hygrometer.

These appear to be well-made (made in Germany, no less) analog hygrometers. I bought two and checked them against a known unit; they were right on the money! No frills, just solid performance. The seller packed them well (and included calibration instructions...that have not yet been needed). They were shipped quickly right after the order. Top-notch seller!

I use this item inside my guitar cases. I really like the size and the fact it is adjustable, it is easy to calibrate and as accurate as my very expensive electronic hydrometer. the size is excellent for inside the guitar case, and with very little effort i was able to make a holder for it. Excellent product which I have recommended to my friends.
