Easy to install no streaks
Size: 24+17.01, Style: 2 piece
No problems installing these wiper blades. They do a very good job of clearing the windshield of water when it’s raining. I have not noticed any squeaks or streaks. Well worth the money.

Good Price. Solid Product
Size: 26+19+21, Style: 3 piece
I ordered these wipers for a 2011 Honda Crosstour. It’s a pretty rare car and I barely see these on the road, so finding these wipers was great since most brands do offer parts for these cars but they are crazy expensive, what I liked about these wipers was the durability and the efficiency you can notice the material was sturdy and wasn’t going to snap off and the efficiency was great. It cleared the windshield without leaving and strikes or making a sound. I would highly recommend these wipers or buying from this brand.
