So after 2 faithful months my VV mod has gone ca-puts, unless this problem has happened with any one else. Please help. No matter what carto, clearomizer, adaptor I use, and any combination of voltage I get the same results. When I go to fire up the mod I don't get a "sizzling" noise from the carto. I have to shake it or tilt it to get it to work, and when it does work it's only for a sec. I'm thinking there is a problem with contact points, I usually clean it often so I don't think that could be the problem. I tried all my cartos in circulation on my ego battery and it fires every time. So I guess 3 ish questions. Has this happened to any one? and can it be fixed? Are there other price friendly vv mods with long battery life out there? if so a pm with mod and vendor would be greatly appreciated. Should I buy a new one? or go with a Provari from vaporsolutions? Thanks for your time guys.
