Tired of digital hygrometers that don't fulfill their promise? You need a Cigar Oasis 4R hygrometer. Accurate to +/- 1% and recalibrate-able! Easy-to-read color coding; 3-day High/Low readings; secure magnet mount; battery included. Order yours now and never smoke a dry cigar again.
Mine was accurate out of the box. Checked it with a Boveda 72 pack and zip-lok. Big size. Easy to read. Ability to calibrate if needed. I like the temperature feature as well. Looks good in the humidor too. I would recommend this product to others.00
