Whoa, I spoke a little too soon, & recalled a false memory - too many setups on this device. To say "NO GAP" was wrong & I'm very sorry to have misled. Just reconfigured to be sure for you guys, and the truth is there is a small gap in 18350 stealth mode albeit small - about 2-3mm. I'll follow-up with some pic's.
Nice, nice, nice Slartibartfast.
When I first started using my MKB. The little points on the button where giving me a strange tactile feeling on the palm of my hands. I was convinced I was taking some of the 18650 current thru my hand. I'm positive it's just the button's little ...... now, but it's a funny sensation I still get when I'm puff'n w/o paying much attention. As an electrician I think I'm overly sensitive to that sensation, as if you can ever be mentally prepared to be shocked.. Anyone who's been buzzed by a 110-120v outlet knows what I'm talking about.
