Title: Buy with caution
Review: I purchased one and it worked great. Came up to nearly 75% using boveda calibration kit. Adjusted easily. That being said, at my suggestion, a friend of mine bought two from this vendor (which I calibrated for him using my kit) but both could not be adjusted. The adjustment dial was broken. Two out of three with problems? I question whether or not the one I have that "works" is accurate given the obvious quality control issues.
