I was quite surprised at the heft of the box pushing it into my garage. Taking the pieces out, it became apparent this is a HIGH QUALITY cart, particularly at its price point. The plastic is very thick and durable. There are pre drilled holes for accessories to bolt to. I didn’t care for the strut assembly as the screws are too close to edges to get help from a drill. Hand tightening the very large screws was a chore! The wheels are also quite nice, and sturdy. They went on readily and the nylock fasteners included for them means they won’t be slipping off. I found putting the top on the floor and assembling that way (upside down) was the easiest to get everything done.
