The problem you talk about has happened on the MVP2 and it's the same fix as with the VV3's. Take a small pen knife and gentle lift up the pin slightly. To me it's no big deal. It usually happens with knock off clearomizers more then with named products. I hardly ever had a problem with my Kanger Protank 2 and Mini Protank 2's. Now I'm mostly using carto tanks which use the 510 connector and I have had no fire pin problems with the VV's or my MVP 2.
Whew, took forever to get back on this forum. They didn't propagate to Seattle, until about 6:30 am on the 5th (today). Was REWLLY mad when I got a brief looksie, and other people had been posting for two hours yesterday afternoon.
Oh, you made a statement? Glad to hear that, only using the iclear30's and mini protanks 2 so far. Will be careful about the knock offs. HOWEVER, since switching to these bad boys, noticed a reaction. Previous set up, halog g6 batteries (both manual and automatic, more than ine color, primarily using halo @80/20, variable pg ratio depending on mix, some 12 mg, mostly 6mg).
Now using mainly mvp2 Lovin it. BUT, started out using iclear 30 with some mt. Baker 65/35 juice, so good, ordered another iclear 30 tank, another protank mini 2 (had one with same pg ratio, tank cranker juice, all mt. Baker juices at 6mg or below), AND another mvp2 (with some mt. Baker 65/35 in 0 mg coming).
Problem, SEVERE rating. Started honkin on some 0mg halo Belgian cocoa mixed with 6mg mt. Baker Bavarian Creme 6mg. MMMM, good. Added some more Belgian cocoa (all in iclear 30 tank), so could do some chain vaping. Developed severe stomach cramps, couldn't eat, couldn't function. (this was the first halo juice on the mvp's, was still using them out of halo gear, no problems.). Pain went away next day immediately when using mt. Baker juice, and using the 6mg halo out of halo tanks. Later in day, went back to halo 0nic in big tank, hour later, stomach pains return (ps, $100 worth of groceries going down the tubes). Go to bed, no relief for eating.
Today, wake up. Pain gone, start coffee. Everything good until puff halo on MVP. Switch back to mt baker in protank, and halo 6mg in g6 mini tank. Now, this doesn't seem to be so much pure pg related, as to pg ratios AND delivery system (obviously more to the punch on an MVP). Anyone know what to do?
