I was very skeptical, but it really did work and saved me about 60$ on wipers for 3 vehicles. You HAVE TO do it in one smooth stroke or you will have jagged edges and streaks!
Works really great will save me money on wiper blades. Would buy again!
Worked like a charm, cut once and it lasts for more than a year now (bought when there was a sale), used it on friends cars with satisfactory resolts. All in all if you have problems, there are 3 possible options: 1) you are not using it correctly 2) you have 10 year old wiper blades with old rubber 3) your windshield is bad and eating rubber
The product worked great, see pictures below. Researched many different types and have had terrible experiences with others. Went into this very cautious. The support team answered my questions fast and went above and beyond to answer them. I honestly recommend this!
