Not to sound like a cheerleader or anything, but I have to give about a quadruple thumbs up to Andy here.
I sent my Nano in for a tune-up (of my own choosing) on Tuesday, 10/29/13. And that's from the East Coast. I now have it back on Monday, 11/04/13. Yes, that's less than a week, from East Coast to West Coast, tune-up, and back again - during Halloween weekend. And that was more than enough time to realize how much I fucking love the little Nano.
I've come to depend on it to such a degree that I'd not thought of it all that much lately. Just as the "tool" that was always ready, day in and day out. That's the beauty of a log vape - it's always ready! No matter what new vape may come out, there is always room for a vape that is ready at ANY TIME.
Yes, it was only six days. But... it was six days too long, if you ask me.
