That would be interesting to hear about, I have only ordered from the actual Solarforce peeps in China, and i just got my first L2 and it's amazing, and the customer service has been top-notch, even with the fun language barrier. I am currently using some generic "900 lumen" XL-M T6 drop-in that came with my Ultrafire 502b (also pretty freakin nice) that I bought from Amazon, (pretty much because I am still waiting on mt second drop-in to arrive), and it's a killer combo for my first quality budget light. Of course I have more stuff on order as a newbie nutball. But the real Solarforce hosts seem to me to have nothing to complain about in any way... I don't know about anyone else, but I'm still trying to figure out how the Chinese manage to charge little or no shipping, and such low prices for VERY nicely machined and produced products that seem to be worth more than their price in materials alone, besides the manufacturing standards. I can get the same UF 502b body that I have for less than $10, and I really can't find anything wrong with it. The quality of the L2 far surpasses the UF, and wasn't much higher in price. I just don't get it.
That being said, I'm about to stop spending the kibbles on nice cheaply-priced hosts ( i am going to end up with too many hosts and not enough drop ins), and just start building my own drop-ins until I am skilled and confident enough to charge my pals $40 or $50 for a custom budget torch they be hard pressed to improve on for twice that amount. Keep in mind, the real Solarforce L2x series have been extensively reviewed here and on BLF, proven to be quite if not completely waterproof, and almost always adored by even the most elitist non-budget flashaholics. For dudes like us that are looking for a bargain and a lot of value, this is a no-brainer.
