Review on Youngine 4-Pack Swivel Caster Wheels - Heavy Duty with Brakes by Richard Miller

This item's description states that casters are "smooth and quiet: these wheels are made of popular non-marking polyurethane rubber." However, the casters are very hard. This combined with a very square profile results in the casters not being able to roll over small objects such as wood shavings, nuts etc. I have requested a refund for the rollers as they are not as described and will not work. good for my application.
