Hot garbage! FSA's crank spindles are slightly thicker than 24 mm and thus incompatible with Shimano BBs (unless you want your BB bearings strained/preloaded so far that there is noticeable drag!). This allows FSA to sell bottom-tier bearings at a 2x premium compared to higher quality Ultegra, and 3x premium compared to the still-better Tiagra RS500 BBs! FSA are banking on the fact that it is cheaper in the short run to replace a BB for 40€ than to buy a Shimano Hollowtech II crankset for 65€. I only bought one of these so I could give an honest review!
Note that this is no fault of bike-components.de, whose friendly and responsive staff have given me every reason to shop here! So far, I can recommend this store wholeheartedly, but I'll avoid FSA products like the plague!
