The 15 mm size clicked into place perfectly with my pump, and the fit feels so secure that I forget they’re even there. My sessions are noticeably more efficient now, no more adjusting mid-pump. Definitely worth grabbing the two-pack.

The silicone is noticeably softer than the pump flanges I was using, and with the 19mm size the suction finally feels balanced. No more pinching or the click-click sound mid-session. Honestly didn't expect a cushion to make this much difference in output, but my last two pumping sessions were notice

The 17mm size clicked right into place, and the soft silicone rim feels barely there once you start pumping. My flange no longer digs in, and sessions are noticeably faster without the constant readjusting.
