It's a nice cart and the wheels are very sturdy. The wheels were a bit tight when screwing in but once attached they should stay firmly in place. Like that 2 of the wheels lock. My only dissatisfaction was that the center seam of the fold of the top shelf doesn't meet evenly from one side to the other. The top lies flat but just barely because the one part of the fold is too close together. Otherwise will be great to use and easy to store.
