As it is thin chair wheels sink in at take a "set " which can make it initially hard to roll the chair. I suspect this will lead to it breaking down (they all do) faster needing earlier replacement. It is a nice size. The thicker (and more expensive) ones were much bigger.
It bends easily so simple to handle and lay down. At the same time it's softer (more pliable) than it should be so indentations don't entirely spring back from chair casters even when first in use. That makes for a bumpy rolling surface over time. The one I replaced with this also Staples' cracked over time.
