Snagged a few of these from the BLF group buy and they truly are fantastic. I'm not a true flashaholic like most on that forum, so I will say those that aren't used to this type of interface are going to notice quite a learning curve, but it's not too bad. Between the manual and the info on the forum every question or issue I've had was quickly answered and fixed with simple clicks or adjustments.
I'm running Samsung 30Q's in them and they fit perfectly with no rattling around inside like some of my other torches. The amount of light these small things can output is insane. Cannot wait for the next versions!
zachzins18650batterystore is also a great source. They are located in Atlanta, GA and they also package their batteries separately so they can ship to Canada.
