Title: HygroSet II is a Great Hygrometer!
Review: I read the reviews about this product and purchased it. This hygrometer works perfectly! I opted not to purchase the calibration pack but rather calibrate this hygrometer using the salt method that was provided by another reviewer. Using the salt method the RH reading was 70%. I made the adjustment based upon the instructions provided with the product and placed the hygrometer in my humidor. I'm using Xikar crystals 70% RH in my humidor. After 24 hours I checked my humidor and the reading was 70%. I recommend this product!
