"Great accurate device"
Bought this item, put it in the calibration bag and it was already accurate, didnt have to change a thing. It showed me just how off my analog was, works perfectly.

Finally decided to upgrade from my analog hygrometer. Opened the baby up and did the salt test overnight. Calibrated it, and she's ready to roll. Very slim so won't take up space. Easy to read. Comes with lifetime warranty and extra battery. Well worth the $$. Definitely recommend. Buy at Famous for excellent customer service.
