So I just had to share, I just received the new stainless steel version V2 Vamo in the mail today. I stacked two 18350 batteries because they were the first to charge and all I have primarily vaped are Joye Ego C Twist batteries assuming they were about as good but smaller and cheaper than anything else. Well I was WRONG!!! All this talk of cartos better then novas etc. While yes to a degree it still holds true but not near as much of a difference. The difference between ego twists and this thing is......... well...... I can't even describe. There is truly NO COMPARISON. If you are into vaping. Get yourself a professional mod I cannot stress this enough and the Vamo will do fine. No battery rattle of course I have them stacked. No issues what so ever and I have earth battery spacer magnets from ebay coming for my 18650 batteries. Using all IMR as well. But my god I just wish I would have known how different of a quality, flavor, throathit on every device i screw onto this thing it was going to be and I would have gotten one a long time ago!!! Folks, if your thinking of getting one of these much talked about Vamos, go to smoktek.com and get yourself one of the new stainless V2 that recently hit the shelves straight from the manufacture and do not be afraid. Unbelievable. I have never been more in vape heaven.
