I think this month's MBR review shows that the big manufacturers don't have that much to fear, since they only reviewed a low performing, expensive Fenix instead of a DX bike light or P7 torch. Likewise WMB, which didn't review a single torch or the DX light. And MBUK did review the DX light, but under a different brand and for 3 times the normal cost.
Like it or not, most riders aren't reading STW, they're reading the big name mags and saying "Oh, MBR says Ayups are really good, I'll get them".
pypdjl: "I think people are getting a bit carried away with the DX light, very good for 50 quid as it is, it's still nowhere near as good as any of the proper top end bike lights."
2 DX lights outperforms a Seca 900, which is one of the better and more expensive lights out there. Lacks the extreme range, but better fill, which is more useful unless you're seriously shifting. And still costs about 1/4 as much. Game Dealextreme tbh- and yes, I've tried both, and a Hope 4. And of course, 2 lights gives better allround results (helmet and bars), and gives you a backup.
I wouldn't trade either for my 2 torches. Or maybe I would, in order to sell the expensive light and buy more torches, and spend the rest on hookers and blackjack.
