Richard ★★★★★ Oct 18, 2026

The 21mm inserts are a perfect fit for me, making pumping so much more comfortable than with the standard flanges. I love that I could get a double pack, too, so I always have a clean set ready to go.

Eva ★★★★★ Oct 17, 2026

Switching to the 19mm inserts made a huge difference—the fit is snug but not painful. I can actually get through a full session without adjusting every few minutes now.

Victoria Y. ★★★★★ Oct 13, 2026

I was getting sore after every session until I finally sized down, and these 19mm inserts fixed it. They pop in and out of my flanges easily for washing, and the double pack means I'm never stuck waiting on a clean set.
