Sorry to take this way OT but I think they like your McClicky switch as well

oo:
Original:
Imitation:
I have a BC10 and the clicky 'feel' is somewhat similar - a bit softer than standard clickies.
AHA! So I
can replace the clicky switches in my TC-R2s with McClickys. Good to know.
Anyway, regarding the McGizmo clone-clip -- it does work well on the lights it comes on, but I'm not sure it would properly fit a Gizmo, or that a McGizmo clip would properly fit a Jetbeam light either, as the clone-clip
is a few mm's longer. I've bought a couple extra clone-clips for use on some Jetbeams that didn't come with them, but I haven't bothered to try to fit them on any other brands of lights and I doubt I will.
From my perspective as a "pro-sumer", I think Don's clips are the best I've ever seen, and I've wished many times I could have them on other lights that I use a lot. While I agree that I would want to get licensing royalties for anything I might design, it's hard for me to get too upset at Sysmax Inc. (parent of Jetbeam/Nitecore/Sunwayman) for cloning what is essentially a strip of die-cut metal. Setting aside all intellectual property issues, I'm just glad to have the best clip design I've ever seen available to me on both of my favorite brands of lights.
I have no idea what Don's finances are, but hopefully his business is doing well enough that these little ripoffs are more beneficial to Sysmax than they are detrimental to him. For my part, I know he's gotten more money from me already than Sysmax ever will. Hopefully this can be chalked up to a case of imitation being the highest form of flattery.
