Query: Poor materials

I purchased these wipers for a 1999 Honda Accord. For the price I thought I was getting a premium product. Both the left and right wipers had defective materials. While installing the pin to secure the wiper, the plastic pin just bent in the housing and did not go through the outer housing. On the right wiper, the housing cracked while I was securing the blade to the arm. I was able to get the blades secured to the arms but they do not clear the windshield without any streaks. I have an e-mail to Amazon to request a refund!! Looking at the packaging it had a 2007 date and I am wondering now if they are old defective wipers. DO not waste your money on these.
