What a neat change from keychain inspired lights. I really like the concept and design. I sure hope we see more of these insider lights. I'm not to keen on keychain lights.
I Have a Nitecore Tube, I really like it. But I can't, for the love of beaver, carry it as a keychain light. So I don't really have a much better alternative to carry it and I usually don't. I would like to know your reasoning on why you don't like them (keychain lights that is).
On a side note, they have some nice solid colors now, so I'll have to get more.
