Pros: I got the 500 lb capacity for $88 - fair price for a useful tool around the yard. Fairly easy to assemble, rolls nicely across rough ground, carries heavy items, looks nice, saved my back hauling some heavy things. Cons: The term \"Heavy Duty\" is a stretch. The metal mesh on the base is very thin - you can flex it and bend it with some finger pressure. The side pieces are equally light weight, don't line up that well, and the release pins to remove the sides are janky and misaligned (but I was able to bend parts in to shape easily with my hands). Basically I would be afraid to toss a 10-15 lb piece of wood into it - as it would likely bend/break the base or sides. I wish I'd spent another $40 for something truly more \"Heavy Duty\", so I could treat it like an appliance dolly and not worry about it breaking. But if I'm careful with this one, it should be fine.
