This hamper is very nice, and fits perfectly in my bedroom. Very simple to assemble, yet seems very sturdy. Although smaller than some I looked at (which were too big for my space), it holds a surprising amount of clothes. I'm 6'3" and it fits an entire week of clothes no problem. The hanging bags make it simple to grab and take to the laundry room, already sorted.
I chose not to use the casters so I can't speak to that, but they are heavy steel that feel like quality casters.
