I buy the Costco ones every winter for about 5 years in a row now. But this year's batch is really bad and squeaky. They started squeaking almost immediately, the plastic edge were also popping out of place. I took the set back to Costco for replacement within a month, and the replacements are squeaky and left large streaks too. Last year's was only slightly better. They really went downhill these last 2 years.
I bought a regular Rain-X set from Target, and they work far better than the Costco Goodyears. I have an Infiniti G35.
