My one and only Nano finally bit the dust so to speak. I only purchased one just to try it out, and at first it leaked like a sieve. Finally after the third fill and leaving it setting on a paper towel, there were no leaks. My son was using it - he is not a smoker (snus mainly) but like a mint flavor we had as a sample which is what I filled it with. Yesterday, he decided he wanted to try something else, so I took the Nano and cleaned it out. Initially when I filled it with the mint, it had two little hairline cracks at the bottom, but the liquid wasn't leaking. I cleaned it out and just to be safe, wrapped a piece of clear packing tape around the bottom. Filled it with a juice and it leaked all over the paper towel, not only from the center but also from the outside. I also noticed the mouthtip would still spin when I attempted to screw it on, and it also was cracked, and seperated.
I love the concept of the Nano and sincerely hope the new batch has all these issues fixed as I will definately try them again. Now two of my CE3's are leaking when they get down to about 1/2 or less....geesh! All is good though...I have plently of Cartos and another vapemail on it's way from SI...ordered some clearos for my X2's since I have never tried them.
