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.

Good product at a great price
Size: 26+17+12.01, Style: 3 piece
I was looking for some wipers that were just like the ones that come on my 2024 Honda HRV and these came up on the Amazon website so I ordered them and the very next day they were delivered to my house!!!!! WOW and they are just like the ones that came on my HRV. Very easy to install with NO adapters to use or parts to take off. All I had to do was take my old wipers off and put on the NEW ones and the price is great too. Also they come well packaged and a plastic guard is over the rubber for more protection in the shipping so be sure to take that off before install, you’d be surprised how many people would leave it on and think that they don’t work properly. Note: Be sure to clean your windshield before you use your wipers cause road scum or wax from car washes will make you think that they don’t work. I had some problems but once I cleaned my windshield really good there was no streaks at all. Now I don’t know how long they will last cause I just got them, may do another review in the future.
