Fits perfectly in momcozy M5

I’m really pleased with this product! It arrived promptly and was in excellent condition. It’s just as described, and the quality is outstanding. It works perfectly and has made a real difference. I’m thrilled with my purchase and feel it’s worth every penny.I’d highly recommend this to anyone looking for something dependable and high-quality. I’ll definitely buy again!

I hate that breast pump flanges mostly come with a standard size of 24/28mm. I needed flange inserts specific to my sizing & these were perfect. The quality is good compared to others I’ve purchased (I.e thicker rubber, doesn’t tear). I would recommend these if you’re looking for a good flange insert in bulk.

The inserts fits perfectly and easy to wash

Fit perfect

Used as directed. The inserts wouldn't allow for a proper suction and kept rubbing my nipples awkwardly in the process. The 19mm flange itself works just fine for me. I was just trying to save some money and I think I personally may be overly sensitive. Not my first baby or time using flange inserts, but last time I didn't have such a drastic over supply and didn't need to pump as much.

I ordered these in 3 different sizes because I wasn’t sure what was going to be the best fit. The sizing guide is amazing, and honestly you can no beat it for the price! I use them on my momcozy s12pro, my momcozy s9, and my spectra. So definitely bonus points that I can use the same inserts for all my pumps!
