I love my MiniProTanks.
If you like any caustic juices that harm plastic, then of course that's the way to go in a small clearo.
But even besides that, while I do love EVODS, I find the ProTank Mini even better:
-Can't explain why but they just seem to have slightly better vapor production
-Unline full size ProTanks, I have NOT had any metallic taste, and have NOT had to remove flavor wick from stock coils
-with EVODS, I've had the tip crack. I've read it's from overtightening the base, but I guess that's a fine line...
Bottom line, PTMini just seems real trouble-free, and works well.
I have a PTMini2a, (the in-between version with removable glass, but a fixed driptip) but haven't used it yet...hopefully it's the same
