Great replacement wiper blades.
Size: 26"+17"+12JP(HOOK)
These were great wiper replacement for my car, very easy to install and way cheaper that buying them at a auto parts store.

Impressive performance at an impressive price
Size: 26"+17"+14BP(HOOK)
I had one damaged wiper, so I decided to replace all 3 on my Subaru Outback. I have read a lot of positive information regarding "silicone" wipers, so I settled on this complete kit as it was a good value for the price and received many positive reviews.
They come well packaged, yet I was concerned that the longest blade had to be bent significantly to fit in the odd shaped box. However, once installed, that blade straightened out and conformed snuggly to the contour of the windshield.
True to the claim, it does take about 30 seconds to install each blade (that is if you understand the diagram and attempt to do so correctly). I had no issues and each blade snapped securely in place. They appear to be well made and durable. The design is clean and they look good on my vehicle.
I've been using them for 2 months now and they work well. They clear the windshield without streaking or chatter. They seem to work as well as other types I have used. The ultimate test will be how long they last. So far, I am very pleased with my choice.

Easy Installation Wipers!
Size: 26"+19"+14BP(HOOK)
Just installed them on my Outback, simple straightforward install. The instructions were simple and they seem to fit well. These wipers were more compatible than the old ones, and the appearance look like they are original!
When I purchased these wipers I thought I had purchased the Rain-X wiper replacements, but they were not. These wipers seem to work when I used the windshield cleaner with the wipers. The windshield cleaning seems effortless and without any noise.

Great Wiper Blades, Great Price
Size: 26"+18"+16BP(D-PTB)
Perfect fit for my 2020 Subaru Outback. The blades were very well packaged and arrived in perfect condition. They clean perfectly. I have only been using them for a month, so I can’t speak to longevity. They cost less than one third the premium blades cost at the auto parts store, and work just as well.

Easy installation, good quality!
Size: 26"+17"+14BP(HOOK)
These wiper blades are great! The packaging was impressive, and I appreciated that there is clear video instructions on Amazon. There is not 15 extra adapters, that you don’t need. Just pop open the plastic cover and slide them on. It was super easy and they fit great.
