Digital HMs are great. I trust you tried to calibrate the other ones with the salt and a little water in a sealed jar and came up way off. The little cheapies that come with most humidors don't work or are basically worthless. I have seen little digital ones for as low as 19 bucks. If you shop around you can probably get one cheaper. I have seen them no bigger than a cigar and as large as the one that I use which is a Radio Shack wireless Catalog Number 63-1030.


Good luck and happy smoking.
