Has anyone tried these? I'm so intrigued. I'm glad that innokin finally hopped on the bottom wick bandwagon. I'm a dedicated user of the protank ( I have the original) but one thing that bothers me is that the seal is so airtight that you have to open the tank every now and then to avoid a burnt taste. If the new iClear 30s (or the protank 2 for that matter) improved on this Id love it. So what does everyone think about the iClear 30s?
