I got one a couple weeks ago. My was blue, not silver though.
Anyway, if anybody needs a review....
Katady Kvapor V81
It does look beautiful and is not a simple stupid tube. It feels great in the hand (no matter the extension, though 650 is my personal fav). It is kind of heavy so the balance with bigger
tanks is there. Great! Works nice too.
What is not nice nor great is that it came as a kit and in the kit was included a kick. Which was not working. And, as GotVapes said to me, Katady didn't bother to send them any spare parts so they can't replace it. Great move from both of them.
Other thing that is not great is... don't get a blue one. Seriously. They come in silver, rainbow and really nice dark blue. But really nice blue is cheap paint and it starts scratching and peeling off really quickly and it's brass color underneath. So it's ugly. For me, it was just a reminder that I wanted to personalize it anyway, but if you are not into painting or polymer clay or whatever stay with silver or anodized.
Mine looks like this now
So.... it's a nice mod, with troublesome paint and troublesome support. But if you want a cheap mech mod that doesn't look like a tube.... it's a nice option.
