I don't know what some of the reviews are referring to that it fits tighter than the Dyson original. It looks, feels, fits and seems to perform at the same level as the Dyson at a fraction of the cost. I almost didn't buy it based on some of the reviews. I was going to buy direct from Dyson but their $8.99 shipping plus $29.99 filter plus tax put the final cost in the $40 range. Two of them cost half. I would buy them again instead of a Dyson.
