Everything negative that has ever been said about these belts is true! They are difficult to put on, they are made of poor-quality materials, they break under the slightest load. If you change the height of the floor, the belt will break. If you accidentally trip over a sock under the bed, the belt will break. After all, I snapped the belt by turning the vacuum on! I do not recommend these belts, stay away from them. Buyer warning!
