Really like the GT-T V2's performance but I could only get it to work without leaking with a nano set-up. No matter how hard I tried, it would leak from the air holes with the large tank. Got one of these (actually ordered 2 by mistake) and it works perfectly. Also really like the way it looks. Never personally had a plastic tank crack but this guy looks tough enough to handle any juice. Can't go wrong for 2 bucks!
