Great product

I use the Cigar Oasis Caliber IV Slim in all 6 of my humidors. Easy to calibrate and I love the slim, rectangular design. Buy with confidence and keep your sticks in perfect smoking condition!

I have used several different brands of hygrometers over the years and the caliber four is absolutely the best! I have several of them in my various humidors and they are reliable and accurate. Look no further, this is the best one out there!
