They're around the price of a fully "pimped" magura (upgraded clamps, lever, tpa, pads etc etc), if you think of it that way, and fully cnc'd! The slaves are a lower profile too, so you get more clearance. Mine gave me no problems, but some of the older ones leaked a bit, and became sieves if they were bled with water. The new ones are far better apparently! And if it does leak (and you haven't put water in it) then they're covered by a full warranty, so you can easily get your money back
