I'm still using them to this day and haven't had to calibrate one yet and most are within 1-2% of each other. I've yet to see a more fullproof way of curing and still have the best cured buds out of everyone I know. :bong-2: The only thing I've altered is since I battle low humidity sometimes even with a humidifier, I've been putting the buds into brown paper bags a day or two sooner to slow the dry.
