I picked one up today & it don't have the rotatable wheel at the 510 connection, glad of that as I didn't even know of that, the only thing that spins is the VV/VW wheel, I have the MVP 2.0 & luv it but got into batteries with a nemesis & then got a Zmax & a Vamo 5, only 1 day of use & I already know this is gonna be a top contender for my devices, either this one, it is made rock solid no rattles, just very very well built, my Vamo I really don't care for some reason I like the Zmax better, but back on track, this is one device I'm very glad I bought, usually takes me a day or 2 to tell if I'm gonna really like it, the VTR took 2 puffs! Lol
