I wouldn't purchase a tool from a company I've never dealt with, or has good reviews from, in this instance, experienced bicycle-mechanics. Which I happen to be one of. And I've never seen, knowingly, a Sette Torx or whatever. There are quite a few outfits out there that make tools known to be good or better than the same tool made by another of the well-known outfit. Such as: Park Tool, Pedros, Campagnolo, Shimano, to name a few.
If I were you, I'd be searching for reviews on Sette Torx before I plunked my hard-earned cash to become a "beta-tester."
