Typical good Shimano quality finish is like the matte grey XTR. Dramatically slimmer than cable Ultegra it replaced repositioned pivot very nice when on hood. Undecided on the deeper curve design i never had problem of slipping off hoods and it makes cupping the tops of hood in a pseudo aero bar position not as comfortable. I now see the complaints of Shimano DI2 lever/buttons being too easy to confuse and understand Srams implementation. It can be reprogrammed to partially emmulate that if desired.
