I ordered those brakes on a custom build. The builder told me when I took possession that he had had poor or no response from Heine on problems with brake squeal. He ended up putting Kool Stop pads on the brakes. They've worked well for me, with occasional scuffing of the surface during maintenance chores. Contrary to sales statements from RH, I haven't found them to be superior to the cantilever brakes I have on a very similar bike; there's a bit of squishy feel to them. IMO they weren't worth the extra cost.
