I do have a paid Subscription to CR so read the whole article. They did not post their findings. I was upset they posted they tested, no report.So you have to be a member of CR to get the full info on test reports. Have a library card? If so, most libraries have online access to CR that you can access from your home computer.
While I cannot tell you right now which wipers are the best, I've watched some pretty interesting youtube video tests. Those have no paywall and should be quite helpful. There were some clear winners, at least of new blades. CR likely did extended wear testing and how good they worked after 6 months of use.
