Product review (1 stars): Flat spot prone. Buy a different roller
These new rollers fit ok and were fine upon initial install, but when I went to do the first load of laundry a few days later the new rollers had already developed flats spots from sitting in one spot.  They are bad for the first 5-10 minutes or so and then improve, but never back to smooth round.  A week later for next laundry day, they have a severe flat spot again.
While purchased a while ago, these remained in original unopened packaging and uninstalled. Once installed, they developed the above problem within a week. Despite uninstalled and stored in original packaging, and problem only developed once installed, seller will not stand behind the faulty product.
