You guys....you're all so funny.
Any VW mod you buy for under $100 is gonna be the same as the other VW mods....goes for VV also. The difference is the problems you're gonna have with them.
Started with a twist, went to lavatube, then found VW with the ZMax. Did the groove, until they recalled them, throw in a bunch of different mechs (siegeli, zmod, homemade mods, Galileo) and you have my history. For me, and only me (I speak for no one else) VW is the way to go. Presently
vaping a MVP V2. Love the thing. Vamo V5 is on the way from china now, gonna do this with it.....
Don't like the tall and lanky look, but I wanted a VW backup and since I like to putz around with mods.......the pic is a proof of concept, no finish applied, and once the new Vamo gets here, it'll get a purty finish.
Your stated choices are not an upgrade as has been stated....your choice is only limited by your funds and imagination.
Luck to you
