Assembly was pretty easy, though definitely easier with an electric screwdriver. 
As others have mentioned, the bins are smallish, but I do laundry fairly frequently so it's not an issue for me. It holds most of a load of shirts and underwear and stuff, and then when it's time I go round up all the dirty jeans and sweaters that are in the "ok to wear again" pile and add them to the load, so I haven't tried putting bulkier items in here. 
The dowels that hold the fabric bins are a little unwieldy, and they don't quite want to stay in place; the fabric bins themselves seem a tiny bit too small for the space and so the fabric is taut and can pull the dowels out of their little notches. But this is manageable with a couple small nails hammered halfway in to keep the dowels from pulling out.
