Review on Effortlessly Move Heavy Furniture With SOYO'S 500 LB Capacity Furniture Dolly Movers And Lifter - 4 Pack by Kyle Robbins

Used this to move a 400lb safe that was flush with the ground. Used a hammer to wedge in the lever, attached a long pole to the lever, then worked side to side adding 2x4s as lifters. Once the lifters were in, I slide the casters under, and moved the safe over rough floor. Still in shock this kit worked so well.
