I got a set from Diesel electric in Riverhorse park in DBN last week. Cost around R220. On mine the drivers side blade was not contacting properly due to the plastic clip mentioned above. Removed the clip after much trying and the blades now contact perfectly. Have to admit its the best blade Ive ever used. No streaks or bumps. I had a good chance to test it yesterday in the rain between DBN and JHB.
