Product review (4 stars): Easy to replace
Our dryer kept getting a hold of strings and ties on the clothes and then twisting up the whole load of laundry.
I had no idea that these slides in the dryer wore down over time.
When addressing another problem with the dryer, I came across some bits of old dryer slides and one that still was intact.  They are very easy to replace, and now the dryer doesn't "catch" the laundry.  It runs more quietly too.
