I wonder what would happen if they were able to open a US manufacturing and repair facility? They would probably be even bigger in the US than they are now if 4-Sevens didn't decide to jump ship and start his own company. I don't know why they even let him continue to sell Fenix lights.
They had a lull for a while I think at Fenix, but I still love all my Fenix lights, starting with the Simple P1 and my latest the TK-35. I think they have some good people there now. They target the general market as much as possible, so there is room for more specialized lights, but they still deliver great value for your flashlight dollar. They have staying power, the others seem to last 2-3 years and then they are gone.
It's a big world out there, even without North America, they could become a very big name. There have been a few bigger companies in Europe sold recently, and I would not be surprised if competition with Fenix had something to do with it. My TK11s are still great lights, but not everyone loves the 18650 cell as much as I do.
So I don't know if they will become the largest and best known; I actually hope not, I prefer the smaller innovative companies that can stay connected to their customer base. I'm sure they will grow though; as soon as they find the right people to make it happen.
