Title: It was off
Product review: It was off 2% when i got it and there is no way to recalibrate it. The box claims its so accurate out of the box that other companies that make hydrometers use it to test they're products. If I was to do it over again I would buy HygroSet II Adjustable Digital Hygrometer instead. If that one comes and is off you can recalibrate it to make it read correctly.
Would you say this review depicts the product in a flattering or unflattering light?
