why didn't you unscrew the top and fill it that way? same way as the cleito, exo and 120?
you have stupid reviewers who have't cottoned onto this fill method either. I had to show my work colleague this when I got his pro tank
I did try that a few times, not knocking the tank. I used it for a long time with my aspire puxos. I just enjoy my Falcons more.
I hated the original cleito, mine would always vacuum lock and get dry hits but the pro Is a great tank.
