I have ProTank1's, T3's, T3 Minis, MiniProtank1, MiniProtank 1.5 (for a couple weeks - it has removeable glass but not tip), and unopened ProTank2.
The Mini and Mini2 are GREAT. They vape well out of the box, they don't leak, they have good flavor, and they're glass.
I like my ProTanks as well, but I DO find I need to remove SOME (not all) the flavor wick, to allow enough
juice to reach the coil.
A couple notes from earlier comments:
1) I don't like the way a ProTank sits on a VAMO. It doesn't quite reach the "collar" so it's supported only by the 510 threads - which already suck. I use my ProTank on other
mods...
2) The ProTank IS ok on an EGO, using the "beauty ring" it sometimes comes with (or you can buy it for under $2). It's fatter than the battery, but you get used to that look after a day or so (at least I did).
