Sweet. One thing I love about my V3 Sentinel is the button is about perfect for me, and I'm sure the M16 is at least just as good. Also really solid and rugged in all modes.
I've been using it all day. The floating 510 connection is very VERY stiff and you have to use some force to push it back into place; I hear that it loosens up over time/use. Those Efest 30 amp 2600 mAh batteries are huge for 18650, so the top and bottom telescoping caps barely screw on and threads do show. The locking ring is easy to open close... a little too easy and just using it has a tendency to close it. The button itself spins a bit and from use and unlocking/locking it, I have to re-adjust it so it fires.
The only mech I've used is the k100, so I am used to the knurling on the locking ring and the non-adjustable button. Just from handling the mod during use, I seem to be spinning the button more than the locking ring, which causes mis-fires. But it's only my first day with it, and there is always an adjustment phase with new things.
** just took out my AW IMR 18650 and placed it next to the EFEST 18650. Same size.
I built the 2 KFL+ clones before work today, and that OHM meter came in handy and reads better than the MVP2, which has been a bit wonky with the resistance readings.
Also, I spent the day with the 18mg nic Bounty Hunter in the KFL+ clone and was fine.
