i live at 5600 ft. elevation. i work at 1200 ft. elevation. ---- EPIC problems with carto + tank. I HATE IT. vision nova
tanks work, but if you drop it - it's dead. vision eternity, also worked, was nice, lasted 2 days until i dropped it at work = dead.
i'm thinking a nice rebuildable is what i want, but i want something that the threaded end isn't SUPER CHEAP like the vision stuff. (when you drop it, and the threads break off and stay in the pv side... = anurism.)
