Review on Precise Humidity Control With Xikar PuroTemp Round Digital Hygrometer, 10-Second Refresh Rate by Johnny Black

first it does not fit into the 1.75 inch hole my humidor has. I was going to send it back but the unit is very accurate as the analog one that came with my humidor is not. i ended up using the supplied adhesive strip and sticking it to a shelf so i can read it through the humidor window. It must be placed inside the humidor anyways so now i have the completely inaccurate analog one up front basically to keep the humidor sealed.
