Cart is great. perfectly holds 20 PD cylinders. the strap is secure. Pneumatic wheels roll perfectly. sit upright on any surface. The clamps hold the hose well. I really like the conical flashlight stand so you don't have to put it on the floor. The reason for only 4 stars is that you have to grind each hole with a drill to insert the screws to assemble. looks like it will hold 2 small cutting cylinders
