I have the Itaste MVP 2 and the vv/VW 3 as well as a Provari Mini along with a handful of Mech Mods. I rotate through the mods day to day, but the Provari is always in the mix. Do you need one for better taste or more vapor, probably not, depending on your feed on top. Will you enjoy using a well made device, in my case, most definitely yes.
