## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great for my spectra pump
*by E***Y on August 5, 2025*

These are the most efficient and comfortable flanges I’ve found for my spectra pump. They have lasted through two babies and many washes. I like the different size options, as the standard sizes don’t work for me.

### ⭐⭐⭐⭐⭐ Great for Spectra S1 pump
*by A***A on July 23, 2025*

These were perfect for my Spectra S1 pump!! My pump only came with one size flange, and I prefer not to use inserts (just another thing to clean), so I ordered these flanges in my size. They are good quality and affordable. No issues whatsoever! Will order again when it comes time to replace them.

### ⭐⭐⭐⭐⭐ Saved me from sore sessions—perfect flange fit!
*by H***S on July 14, 2025*

If your pump flanges are too big and you're wondering why your sessions feel like medieval torture—these inserts are your fix. The 18mm size helped with suction and comfort, and they fit snugly in my Spectra parts. Easy to clean, too. Sometimes it really is the little things that make pumping suck less.
