I bought this sorter to replace another brand whose fabric after 8 years was starting to deteriorate.  The bags filled to the top are just the right size for my medium capacity front loader.  I love having 4 bags instead of 3 for when I have delicate or unusual items I don't want washed with other things.  The rollers are smooth.  The only con is the bags will often lift off the metal bars when I am pulling dirty laundry out.  For a top loader it's nice to lift an individual bag and dump it in.  The bags can also be removed from their hangers and laundered if needed.
