Wish I could find an RDA like that in my box :>) This will probably be my next purchase. I'll go for the clone though because I just paid $60 for a Vulcan and had it for a week before it rolled and fell off a 30" high desk onto a linoleum floor and the threads stripped out. Provari has their "P3" connector coming out and I hope the rest of the industry will follow - the 510 connection has been a big frustration for me.
