Perfect replacement wipers
Size: 26"+14"+10-1(PTB)
These are fantastic and fit my car perfectly. I was a little worried but they went on easily and were the perfect replacement. They fit against the glass and don't cause any smearing. I was thrilled to get them so quickly because we had another storm coming and these worked fantastically. I can see out of my windshield. If you're on the fence about these, go ahead and order, they work great.

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.
