I have used i06's for a long time now and always loved them. I got a order in when the site was briefly up and then another batch this last week and the draw on all of these is much tighter than it has been. After about a week of vaping on them they become even tighter and almost impossible to use in my DCA. I'm wondering if they have changed or if I just got into a bad batch on these orders. I also have a buddy who is having the same problem with his and its not just like one or two of them we both run about 5 i06s at a time and went through about 15 of them total.
