I was debating on getting an MVP or SVD from itaste. I have other tube mods but no telescoping devices. I kind of like the long lasting internal battery on the MVP and seems like a pocket friendly device. Kind of looking for a work device that with VV or VW that fits in the pocket. I like the fact that the SVD telescopes and has VV/VW. I have recently discovered the Kanger EVOD clearos and have been using them almost exclusively with a few carto tanks. I have read a post on FB that the EVODs don't work on the MVP and they can't breath. Anyone else experience this?
