I too have been using mine pretty much exclusively for 3 weeks now. I love this little thing and wouldn't hesitate to buy another provided the reason wasn't this one going up in smoke.
Mine came from an eBay seller in Mason IA.
Size wise comparing to the
smok line or
ipv mini or even the segelei mini this thing is just tiny. It's an
istick with girth and it fits wonderful in the hand.
Those on the fence imho I think it's worth the risk. Just be cautious when your going to be away from it for awhile and that might give you peace of mind.
