I'm quite tired of every piece having completely different reviews on it, these things are mass produced, how can they vary so much? That being said, I would much rather have the glue free, glass tank of the mini Protank 2 and most of what I read about it is highly positive and that it is better than the full size Protank 2. Enough of being put off by bad reviews and time to try for myself, just waiting on my in store credit at Myvaporstore to go through.
I have two protank minis and I ADORE them. Good flavor, good vapor, good everything. I'm one that hated the protank 2 as well, but I have always loved my minis. Heck I even love my ProTank II again now that I put an Aero base on it. I use the iClear 30s tanks, and I do enjoy them. Good flavor, good vapor tight draw but not too tight. I have three of them running right now. The only thing I don't like is their plasric. But I haven't had them melt with any fruity juices, so they are living up to that claim. Hate the iClear 30, limited on juices, you have to swirl it a bit to keep the wicks wet...and you can't change out the drip tip to a standard 510 tip. You can with the iClear 30S but it is very loose.
The Protank Mini is a solid choice. I have never had a gurgle, leak, or any other issue with them that wasn't caused by my own error.
