Hello! I started on the V2 and am quite happy with the build of the batterys, however, I am not a fan of the carts so much and decided to get a pack of three liquimax clearos. They work okay, but I have nothing to compare them too just yet, the only big complaint is the drip tips leak somewhat and don't exactly seat perfectly. I can see easily them coming apart in a pocket and making a mess. They work WAY better than the carts as far as I know, and I do like the liquid being visible like a good clearo should.
Due to my vaping style and consumption, I have ordered an eGo Twist and a set of Stardust clearos for a better vaping experience, plut batt time. With the two V2 batts I have, I go through a batt within a few hours of periodic vaping, so one is almost always on the charger. I do like how stealth they are, it looks much more discrete than holding a lightsaber to my face at work.
Just my two cents,
I really like them, just need more power and juice in a setup, plus one that wont leak so easily.
