Like it is definitely strong. The wheels move well and can easily support a lot of weight. I like the method of folding the handles better than the cables used by Rock N Roller. Dislikes: Fasteners on the bottom. One broke off on first use. the latches on the Rock N Roller also have issues, but I was surprised they broke right away. I also don't like that the button to expand the cart is on the back. You must turn the cart over and reach down to press this button, pull the cart up AND try not to hit your face. Overall: If you're deciding between this and the Rock N Roller I think this one is stronger and the grips are a lot simpler than the cable system. Rock N Roller is slightly longer, so take that into account when making your decision. But I like big wheels and this cart is strong and easy to move.
