Since the gen 3 L1 has just hit the market, you'd think anyone who was deeply dissatisfied with their light would return it for a refund. There aren't a lot of good reasons to resell new goods when they can just be returned.
I have absolutely no evidence to indicate this is going on, but my cynical mind is wondering if someone or other offloaded a bunch of L1s real cheap a while back. Reselling goods bought at below market prices does have a clear profit motive.
