Great review. I was one that won too. Used it this weekend and worked great. Everything you said covered it to the T! From all the good to even the ending where I wirshed it was a 510 too.....i was able to get an adapter and slap on a slim vivi nova. Really loved like you said you dont and have to prime....just puff and pound. I have people here in hawaii wanting this from me. I keep telling them nope because this is like the only thing I have ever won. Lol anyways good review. And just to afd I like that there is no button and that obnoxious bright light...perfect for vaping at the movies...,aloha! And mahalo V4L
