Yeah... We ran ours for about 15 minutes and started to notice the rubber starting to *chip* (not sure of the technical word...) Granted, our rollers aren't fixed yet and are dragging on the floor, and we haven't tried it on the carpet yet, just simply using tile floor.. But still, they seem to wear fast.
We will fix the rollers on Monday and I'll let you guys know exactly how we did it so that other teams with the same problem can fix theirs. Sunday is our day off (mine at least
)
