Thursday ordered, delivered Saturday, there is nothing quicker. The whole housing fits exactly, but the small tabs on the snapper are a bit too high / too long. Therefore they could not engage in the intended counterpart on the housing of the vacuum cleaner and the filter slid independently on this side slightly upwards. I have both tabs on the snapper of the filter with a sharp knife from smoothed "above", so some of the "height" cut / worn. But very little !! This has claimed for 2 filters only a few minutes; the consideration had lasted a little longer. Now raced both filter properly with a "click", exactly as it should be yes. One point deduction for fumbling, but the price is unbeatable, especially if you have a delivery charge multiple filters (I had 2 pieces) ordered.
