I wanted to share my experience about changing the rubber wiper blade of my i30's gd in front.
For 3.5 years all my wiper blades were working perfectly.
My car is the 2013 model and the front driver sided wiper blade rubber was split
a few days ago and I didn't want to buy new wiper blade. So I bought a cheap 650mm=26" rubber refill of 8mm heighl
with cost only 1euro per item and I have installed it today and it's working fine and silently like the original! It was the first time
that I have installed a refill and it took me 5 minutes. It's very easy process even for amateur.
The refill is something like that

So no more new wiper blades here, only rubber refill.
