Product review (5 stars): great replacement
buying another one, last one I bought was a perfect replacement.  I don't understand some of the other reviews, apparently they either ordered the wrong part for the vac that they own or got an incorrect part and should have returned it.  It fit just fine into the canister on the vac, you have to know how it fits and put it on correctly.  If you know what you are doing, you should have no problems
