Yeah, mine read 85% for the first week after seasoning, and I added cigars when it got to 70% which took another couple weeks.
In the end, I think it's just too poor of a seal to hold any reasonable rh, so I emptied the contents into my big humidor which is holding nicely at around 64%, and you can feel th wood rubbing when yo close the lid.
Gave the small one to our former Army WAC for her jewelry.
I friggin love cigars
