I like that a lot. 18350/18650, reminds me of the old school mech mods. Looks super clean.
I'm excited for mine. I generally use tubes only at my desk, but here's some thoughts he had:
[18:55] The mosfet continues firing for half a second after you release the button (shown at 19:23). He says it isn't a safety issue, but because it's not expected it makes you cough. The actual performance is pretty decent though, hits as it should. He's using a 0.20 coil on a 18650.
[22:40] There is no on/off mode. The mosfet just fires anytime you click it. It's a very small and sensitive fire button. It can fire in your pocket or even just sitting on its side on your desk.
[Mentioned earlier in the video before he gets into it] The lock works by turning the latch at the bottom. All it does it add a gap between the battery and the contacts making the battery rattle when you hold it and never touching both at the same time.
[25:40] He says this twisting mechanism may not good for the battery, constantly squeezing and unsqueezing the battery. But also, it's hard to screw and unscrew the lock. It's stiff and sometimes when trying to turn it you end up just unscrewing the entire base.
Pros
+ Beautiful
+ Insulator rings
+ Performance (i.e. how hard it hits)
+ 18350/18650 support
Cons
- MOSFET continues firing after release
- No On/Off
- Locking mechanism is stiff
I'd add that the locking mechanism could probably get really loose eventually and may tighten itself as it rattles around in your bag or pocket, causing it to autofire.
