The carts are make of decent strength of plastic, especially considering the price. The directions are easy to understand and the pieces snap together firmly.  I think the price is pretty good for what you get but I kind of think the company should invest themselves into improving on the larger cart in some way. I just can really think of no use for that really narrow smaller cart. It’s kind of top heavy it’s so narrow. Each shelf will hold 3 large cans of Dinty Moore stew.
