Love that these came in super fast and were ready to be washed and used! I got both 14 and 15 mm flanges and they both work well for me!

These made it easy to measure and determine what flanges I needed to purchase. Ended up sharing with multiple girlfriends when they had their babies. Definitely worth the price!

I like that it’s made from a durable material.Serves you in the long run.

Worked and held up for over a mitnh

Good: durability and cleanliness, easy to read.Bad: smells horrible, no instructions included. I wasn’t sure if numbers were the correct measurement or the flange size.

They get 5stars because they saved my poor nips and that’s worth a lot. So I have now bought 6 sets of these which 5 oh were EXACTLY as described and work super great all sizes were there. Well one of the packs which happened to have 3 of 1 size and only 1 of another which happened to be the size I need, so that’s a bit frustrating but like I said the other 5 I bought were exactly as described so just make sure you make sure all sizes are accounted for in pairs.

I got the variety pack of 2 each, which were a great deal. But they don't fit well in the spectra and medela 24mm flanges, or at least the ones I need (19mm and 21mm) don't. I'm going to try them in the 28/27mm flanges, but I don't know if that will work. How am I the only one with this problem.

This product was recommended to me in the hospital after giving birth by a lactation consultant. After using them to find my correct flange size, I ordered new flanges that fit correctly. Now, milk output is much higher and pumping is so comfortable.After initially using them to find my correct size, I now use them permanently in my portable, wearable pumps. I am so glad these were recommended to me-especially for my peace of mind as a clueless ftm. They are worth it!
