I have heard that the tubing pops off rather easily for the washers.

Never had any bother in the almost 3 years ive had mine.

 

try cleaning the blade when you wash your car.

 

Just fitted the Polo one to mine as the original fell off. Its certainly not as good...

**Always** swipe the wipers to clean them when cleaning the car.

 

Otherwise it would be like trying to clean your car with a dirty rag. Well would you ?

 

Never, ever had to bother changing the rear blade, its still OEM I think. The above just works.
