I bought the scrubblade because I had tried every other windshield wiper blade out there and I always got streaks which made it hard for me to drive in the rain. I was not sure what to expect, but the product sounded promising so I tried it out and I’m so glad I did! For the first time in 4 years, I have clear windows again! And they don’t even cost much more than the other brands! I bought the heavy duty scrubblade and they can clean off almost anything whether it’s mud or snow. I’m very happy with my purchase and will be buying them exclusively from now on.
