These fit perfectly and the seal is noticeably tighter than my old ones, so pumping feels more efficient. Glad I grabbed this two-pack to have a backup ready.

The seal holds up fine on my cups, but I wish the set came with more than two for the price. They work as expected, though I can't tell if they're any better than the originals that came with the pump.
