You realize that UltraFire is itself "fake", since it is taking after the name of the original SureFire brand?
Yeah, it's been awhile so I'd kinda lost track of who was copying who.
I also got the feeling, from reading CandlepowerForums (and occasionally some of its clones), that there's more than a little woo-woo and/or snobbishness involved in many cases. Try admitting that you've got a perfectly decent torch off Aliexpress and watch the fireworks...
