This is the ULTON 22mm version. Refilled it about three times today. I'm experiencing the usual Dvarw flavour with no leaking, dry hits or any other issues.
As Klaus Jedelsky noted, the first thing that hits you is the upgrade in terms of aesthetics and overall quality. What a difference a glass tank makes. And finally, a Dvarw drip tip that isn't butt ugly! It's very comfortable, and I'm definitely ordering the black and clear versions, to replace my white one.
All in all, if you like the Dvarw, definitely pick it up.
