Started my DIY a month ago and had no intention of rebuilding heads. Yesterday though, I figured out why all my mixes tasted like crap. My Kanger T3s are crap. I have some decent juice If I use the old Vivi Nova clones that came with my Vamo, but through a T3 . . .crap. I'm going to recoil and rewick the T3s with supplies from LightningVapes and hopefully solve the problem. I guess my point is, I've used 4 or 5 clearos or tanks and I like the bottom coil stuff but T3s suck. I do have an MT3 that is fine. . . go figure. Never had anything that leaked. If rebuilding the T3s doesn't solve my problem, then the next step is ProTank. From what I'm seeing now, the ProTank II and the Davide are the two top tank choices. Now when do we get to the place where we can stop spending all our bread on hardware . . . hmmmmm, maybe after the ultrasonic cleaner . .
