I originally bought a jumbo cart to haul groceries on the bus system only to find it's way too big so I bought this one and it is sturdier and just the perfect size for plenty of groceries and fits on the buses without blocking the aisle or other carts or walkers that need to get on the bus. I find that It is best to reinforce the welds at all the upper point and four lower points where the frame connects. I used jumbo paper clips and it has worked out just fine. I made the mistake of over-filling it with many 2 liter bottles of soda then pulled on the front of the basket and one of the upper welds came apart. I wrapped a paperclip around it and at all 6 points and now i can carry any weight with it.
Much sturdier than I expected - strong large wheels. No tools necessary for easy set-up. Fold up and open up only require one foot and two fingers - no damage to arthritic hands. Only two wheels means when I set it up for loading it won't roll. Also easier for small loads that are too heavy to carry - no need to bend almost to the floor to get them. I have used it for a variety of tasks including laundry, library, and for dragging groceries, etc., into my apartment from the car - but not at the grocery store.
