Hello all ProVari, users.. Mine came in last night and I'm in bliss but still wanting more (go figure). What I mean is I am using the Boge 2ohms on it and can dial it up to 3.5 beyond that not so good. Have some SR coming so will see what they will be like. Find the device extremely easy to operate and love the functions on the ProVari, very well made and enjoyable. The battery charger that came with it has me a bit puzzled as I put the two bats in and of course both bottom red lights came on, then after a period the light on bat chamber one turned green but the one on the right remained red. So I switched bats from right chamber to left chamber and showed green on that too, hmmmmm puzzled on that one as I would think that the charger ProVape sent with the unit would illuminate green on both chambers when charged, perhaps green/red means both done idk.. Looking also for an adapter to fit the eGo on the 510 ID thread, I see that Provape has and now wishing I saw this before I ordered as coming from USA to Canada for 9.00 plus shipping kinda silly and a huge oversight on my part. If anyone knows a Canadian vendor they can suggest for this adapter then please mention. I also see that most are using the tank systems on the ProVari. I'm still leaning on the Boges, but would like to dial it up.. Cheers!
