I bought these last week to replace the failing wipers on my 159.
The old phrase of "You get what you pay for" is soooo apt and true!
Great delivery, great price, pants product.
Firstly they were very difficult to fit, the spindle on the wiper arm was slightly larger than the hole in the replacement blades, but after a bit of lubrication and brute force they went on.
Great I thought. Set off with the wife and two kids in the car, got on the M5 and used them for the first time. 50% of the blade doesn't even come into contact with the screen!
Stopped at the services and tried to bend the arm, check the blades etc... No use.
Got home, eventually, and took them off and fitted the old ones. Unfortunately I managed to snap a small piece of plastic of the centre fitting on one of them. So the company won't refund. Grrrr.
Have ordered a set of Bosch Aero blades instead! Well worth £20.19!
Don't say you haven't been warned...
