Been using the VT all day. If you like the vivi nova, you'll like this. It is just a mini vivi nova with a different atomizer head and mouthpiece. Also, the base is ego
threaded only and would not connect to my vamo without a 510 to ego adapter because the ego sleeve is too long. You can take the VT atomizer head and put it in a mini vivi and use it with the VT mouthpiece. I'm using it that way now because my mini vivi has a 510 connection and works fine on my vamo without an adapter. In my view, they could just sell the VT atomizer heads and VT mouthpiece as an add on to the mini vivi nova. I still like the kanger T2 better.
