Not sure what to compare to. This is the only belt that fits this vacuum and it seems to do fine but I do find that it gets "torn" easily as its just a thin plastic belt. But while its attached it works fine. You can't accidentially vacuum up anything big or if the rug's tassels get caught in it it will tear the belt. I wish they were more durable but not sure they would be able to do their job if they were thicker, you'd have to ask the engineers about that.
