I have used these carts for everything. At 1st to bring projects home from my students so I could grade them. Then to haul photography equipment for my daughter's business. Now that I'm retired I use it to get my groceries into my apartment and for my cat litter.
The small box locks (use when close box) are week. Too hard to handle 6 one gallon water bottles carrying. One bad design is the side frame color black (other color is better is find at night).
I feel the mobile utility cart is a good purchase. It is structurally sound and durable easy to fold and unfold and is lightweight enough to haul around as needed.
