I also dislike the "ideal" markings of 70% rh since I feel "ideal" is whatever you prefer and also should be relative to ambient humidity where you live. I keep mine a bit drier since our humidity levels here are so low. My cigars don't burn as well the more humid they're kept.
So there's an opinion for ya but it's only that. I haven't actually used the Don Salvatore hygromete
Thanks for the input jwacky! I got the Don Salvatore to replace the crappy analog unit that took a dump when the little spring broke. The info sheet that came with the DS said it was calibrated from the factory, but that turned out to be incorrect. Been in the bag for a salt test for 26 hours now, and still at 70%, so it appears that it's 5% off. The cabinet humi it's going on has a digital in the top section and one in the bottom, so I got this purely for esthetics. But I still want it to work. MSRP of $40.00 now, got this one on the Mash for $20.00 about a year ago. Since I keep mine at 70%, the 68-70 "ideal" markings work OK for me. I was just curious if anyone else had one that was off, even though the claim is "factory calibrated". I had absolutely no intention of interrupting the gun debate.
