From Diamond Crown, makers of some of the world's most luxurious cigars and humidors, comes this worry-free, digital hygrometer-thermometer. Its slim design takes up hardly any space in your cigar humidor and the stats are shown in easy-to-read numbers. Battery included.
My hygrometer is about 6 months old and it too has gone bad as the previous review also indicated. Save your money and buy something else.
