The AVS2/UFS system will change every thing about the way you vape, its better than dripping, its consistent vapor with out the mess.
I would agree, it is better than anything else. And in the long run easier to use with less mess and better performance than any tank or feeder I've used - and I have them all pretty much.
However, I would caution potential new owners to expect a LARGE learning curve. I'm a geek, and I had disappointing use and performance for the first three days. Even with Bruce from CoV's patient coaching at VapeFest, I was either leaking or getting horrible dratty. It wasn't until I had it in hand, and watched Igetcha69 and Imeo's videos on the UFS again with the unit in hand that I 'got' it.
It does work, and work amazingly well. A marvel of mechanical engineering really, and a work of art. Just be prepared to have to master how the air control and liquid control rings work in practice for your atomizer and juice to get to that consistent vape. Since then its been vaping nirvana; no leaking, no dratty, wonderful flavor and amazing vapor.

Don't be discouraged when you first try it, keep at it. Its
SOOO worth the cost and learning investment.
My biggest mistake was thinking I wanted the air and liquid wide open. I actually get more vapor and more consistent juice flow with them restricted quite a bit. At this point I'm familiar enough with it that I lock them closed for the night, and can pick it up in the morning and spin the rings to exactly where I need them to be.
