Looks pretty nice.
I like the flush side-mounted switches and the dual emitters.
I think the biggest problem might be the magnets. It looks like the tail has some pretty strong magnets keeping the tailcap on. That’s good for waterproofing. But not necessarily a good thing next to your keychain since the magnets might stick to something on the chain.
Also if you ever accidentally stick this light in your pocket with your wallet say goodbye to your credit cards or anything else with a magnetic strip.
