No Harm in trying it & I Hope you get on with it
- it's always useful to have lots of tanks at hand
The protank series of tanks are nearly all glass (except for the unitank, but we won't go there, it hasn't proved to be very popular!) so you can use any juice you like in them and not worry about cracking.
The protank minis are the smaller tanks, they hold about 1.6mls, the protanks hold about 2.5mls - the protank '2' (or protank mini 2 - '2' is actually a series model number, ) was the first model in the series that could be dismantled completely - great for cleaning and if you break the tank by dropping it you can pop in a new glass tube (I use different colour tubes and drip tips on mine, but have only broken one so far!
)
The latest, and some say greatest protank so far is the aerotank, this has a dual coil (BDC)instead of the single coil used in the other Kanger tanks so far, but the coil can't be retrofitted into the other protanks (I'm sure I did see an adapter for it t'other day, but for the life of me can't think where).
Some people find the protank series 'a bit airy' on the draw, but if you already use evods then you won't notice it much. I've also found occasionally that they charge through a juice fill quickly - but I do suspect that it's actually me chain vaping and not noticing because I've just got a really good-tasting juice!
If you do consider purchasing a glass tank, then before you buy also have a look at the Aspire BDC's and the Anyvape Davide tanks too as there's a lot of good reports here on them: here's a P.Busardo review on the former (a highly respected reviewer) and a VapinGreek (as before!) review for the latter

Last but not least, if you are flash for cash then have a look at the Aspire Nautilus, again it seems very popular and is reviewed by POTV's very own Todd here
