Ok so I am hoping I do not sound like a total loser or that I am 135 years + but I do have a condition in my hands, I am wondering if my grip weakness is the problem with my mini nautilus tanks? I struggle so much to open my mini nautilus tank to refill that I have never experienced with any other clearo I have ever owned. Even the tiny little mino clearos I use on my volts are no problem for me. Please tell me other people find it hard to use nauty mini tanks?If not , what is the trick?
