Review on Schioppa GLEEF 312 NT Non Marking by Tim Paolucci

White nylon won't mark floors, but wheels are V-shaped. "Molded with all the weight in the middle 1/8" which will dent the floor unless you maybe put soft rubber roller bearings under the wheels, which defeats the purpose. Unfortunately, we didn't see any dents until 12 hours after the return window closed, leaving us stuck with $70 worth of useless wheels. (They also don't work well on concrete)
