I got the MH10 V2 today and it's super. I also have an MH12 Pro which has two switches like you said on your S model. Eye burner for sure.
What I like about the MH10 V2 is that it has only one switch and comes with a really nice plastic holster which has a clip and can also be molle strapped. It holds the light securely and has a big cutout so the switch is protected. Also where the bezel bottoms out in the plastic holster it is narrower than the bezel, so the flashlight has no chance of dropping out. Runs on 21700 so I can share batteries between this and my MH12. It can also use an 18650 or 2xRCR123A or 2xCR123A. Eats anything
Despite the ratings, it's really bright and the UI is quite ok. This one is a winner for me.
An easy way to spot the proprietary battery requirement is that they put an i in the model name like P20i. I just avoid those.
So far in Nitecore I have a few SRT3, a couple MH10 V2, MT10C (next best thing to my old favorite SRT3), couple of MT2A which I kinda hate for various reasons, an MH27 (good, crazy colors and a nice fabric holster) and the MH12 Pro.
Agreed, wish they would go with screw-on clips like on the SRT3. These spring clips are totally untrustworthy so they go in the drawer.
oh meant to say I like your quote from John Cleese. My buddy quotes Mr. Spock "In an insane world, a sane man will appear insane"
