I bought front wiper blades form my BMW and it was an excellent item and no hassles at all. This is not the reason for giving three stars. Unfortunately, I bought a pack of chrome valve dust caps too - biggest mistake! I did not have to check air for couple of months and then when I tried to take them off, all 4 got fixed to the valve! I managed to remove 2 of them but not the others - I had to change the pressure sensing valves on the BMW. Not a cheap option. These chrome valve caps should be withdrawn from your site!
