I've had the GGTB in matte nickel and so far so good! I've noticed a few dark spots where my fingers are constantly attached, but I haven't wiped it down with water like suggested yet. I'm just in love! I have the tenergy 3.0v RCR123A batteries, but I keep hearing about these 17670 aw's. In what way do they improve the vape? Vapor? Just how long they last?
Sorry for off topic
