I've spoken with Fiore on many occasions, and it's sadly unfortunate about UPR ripping off his design. In the end, he didn't have a patent, it's his loss, however get his original piece, it has amazing quality. I tested a set he sent me and wrote a full writeup. Click the link in my sig for that.
In short, it works very well. However, perhaps my favorite aspect about the fiore fwa, UPR fortunately didn't rip off. the fiore unit has a rotating sleave inside of it where the cable slides into. Because of this, the clutch cable does NOT hang and make the fwa stick like all other fwa's I've tested. Usually, once you get some good preload dialed in, and that cable tightened, the fwa becomes so stiff to turn, that you literally will scrape the skin off your fingers trying to tighten it more. (this with all other fwa's) Fiore has that internal sleave, so it rotates very smoothely around the cable, no sticking. Hopefully you'll support his product and not buy from upr.
