I love my fleece flippers, I only wish I could afford another set! I only have 2 issues with the Uhaul liners.
The 1st is probably my fault, they shrunk a bit, so the edges aren't as absorbent as I would like.
2nd, I wish they where sewn like the cases. Because they aren't I some times have issues with the edges bunching and it's generally time consuming to straighten it. I've figured out a way to avoid this problem, I use extra coroplast inserts on the outside of the uhaul liners (like a sandwich) when I put the fleece cases on, and then pull the 2 extra coroplast inserts out.
