Another mod I picked up from 101vape after VJ pimped it This one is a little fiddly. Not bad though. In 18650 mode with flat top sony vtc5 in it you can just see threads of copper tube. Looks better in 18500. 510 connection is a tad grinding but may smooth out after putting on and removing tanks. Magnetic switch is pretty smooth and doesnt need to be hit dead center to work good. Not reverse threaded so watch bottom doesn't screw off. Looks great and fits in hand well and with swirls and edges on it you feel secure using it. I will defiantly keep using and for 22.00 another great buy. I'm sensing that I am headed toward liking mechanical s more than vv/vw. At least when I'm surfing the net or working on computers
