Hmm. What's wrong with me?
20k miles. Bought brand new in August 2016.
My wipers already streak. All of them. Even the rear.
I got just shy of two years out of mine, and I really pushed em to the limit. We also don't get much of any rain out here.
I replaced them with Rain X Latitudes, and am definitely sold on them. Not that the OEM ones were necessarily bad. They just were no where near as good as these.
