Good product, great customer service

Cigar Oasis quickly replaced the first hygrometer I received that was just outside the adjustment limit, and the second one works great. I plan to buy more as needed for my other humidors.

Hydrometer replacement

Very happy purchased a Oasis IV Digital Hydrometer. First one did not read right and went over the 6% to correct it. I called and a replay was sent right away. Very pleased and would purchase from you again.

I received the Cigar Oasis Caliber IV Digital Hygrometer in a timely manner. The instructions are clear and easy as is using the hygrometer.I used the Boveda 75% Calibration packet to calibrate the hygrometer. The hygrometer reading was 6 points low which is the maximum adjustment for the device (+ 6 to - 6).The Cigar Oasis appears to work well and I will probably buy another one.
