Review on 🏋️ Vestil SDOL 2 Capacity Length Height: Optimize Your Storage and Lifting Needs by Michael Powell

They're very durable, but furniture or anything you move will slip when you try to maneuver it. This is very frustrating and slipping can damage the item you are moving or fall off and injure you. I solved the problem by putting a sticky lid on top that kept it from slipping. They are heavy and would be perfect if it wasn't for the slippery surface. I wish I could give a better guess, but the safety factor is too obvious.
