I have a new favorite tank. Easiest single coil tank you can build on. Plus it has juice flow control. Mine was very stiff and I had to turn the whole tank to get it to turn, but it does turn. I put a stainless steel staggered clapton in it and it is a more enjoyable vape than my griffen with the same wire in it. I'm running a max VG liquid and I can watch the bubbles go up the side. There's a V2 that is dual coil, but I wanted single coil, so I went with the v1. The only other issue was that the top cap stuck to the top piece for the tank and I had to use pliers to separate them. Once it was rinsed and I put a little juice on the o-ring it wasn't a problem any more. The juice flow control is just as much of a pain as ever though.
This was rip trippers top single coil tank of 2016. Many others have said the same though. so Even if you don't like Rip, it's still a good tank.
