Product review (3 stars): Bad fit but better performance
Like others have said, these are a poor fit compared to the older style paper filter. But they work better than the honeycomb type pads. So you have to choose between better performance or better fit. The quality control on these is also bad. One pad in the set of 4 was a different length and doesn't completely fill the space, where the other 3 did.

It helps with fitting if you pre-bend the pad, keeping the side with 3 plastic beads to the inside. Also follow the instruction sheet provided and keep the top edge inside the basket lip.
