One wiper perfect, one ruined completely
I bought the Ecocut Pro to try it out, as buying new blades is a pain.
I used the device on my main blade and it worked perfectly, cutting off a long strip a couple mm thick and now that wiper works as new.
Then I used it on my second wiper and the blade completely stammered. I attempted to go up a thickness, but it would not improve the situation. That side of the window is now left in raked streaks of rain water, in the style of a Japanese garden, whenever I have to use the wipers.
Since I have paid the price of a brand new set of wiper blades, I will attempt the use of them again, but only when I have already bought another set to go on, in case it messes up again
