Title: Defective unit
Review: I guess the company who's distributing the product (Quality Importers) forgot they had the word Quality in their name. There seems to be a few defective units of this "HygroSet II Round Digital Hygrometer for Humidors" making the rounds (pun intended).Anyway, I made the mistake of trying to calibrate the unit BEFORE testing the calibration button which just did not work. Turning it either way did not change the humidity display reading.I am glad Amazon has a good return policy and that I am on the free 2-day shipping Prime plan (Amazon Mom plan for parents, new or not!).After 12 hours calibration, the display was showing 71%, so I was not going to use it as is.The temperature display - which incidentally shows Fahrenheit and Celsius - was right on the money. I bought it for the humidity reading...I ordered a replacement unit, if it fails, I'll write another one star review and I'll ask for my money back.
Is this product review negative?
