10PCS Flange Sizing Kit, Silicone Flange Inserts 13/15/17/19/21mm &Nipple Ruler&Cleaning Brush 24mm Flange/Shield, Compatible with Momcozy S9/S9pro/S10/S12/S12pro /Medela/Elvie

Good product. Easy to use. Multiple sizes.

Works perfect with my wearable pump and also my Medela harmony pump!

This is a good first step to figuring out your size when pumping. After a while of breastfeeding/pumping your size changes and it’s convenient to have the variety of sizes. They’re easy to clean but I’ve noticed them getting a bit cloudy after washes and steam sterilizing them but it’s probably just because I have hard water.

I was worried that the flanges would be too long for my Elvie Stride, but the title was accurate when it said it works with a handful of wearables! The only downside is that you have to use the measuring guide that comes in paper form with the kit, you can't use your own. I tried to use a silicone sizer and that measurement compared to the paper insert was very different. The sizing was accurate, but you can't ever throw that paper away!

I have a wearable pump and really needed smaller flanges. I was measured in the hospital but wanted to double check so the measuring guide really helped. The sponge is useful for the small pump parts and also bottle nipples. I like how each flange size came separately packaged so they can stay clean in the box.

This is a great tool to make sure you are using the right size flange. Making sure the flange size is correct is very important when it comes to making sure you're maximizing output as well as making sure you are comfortable during pumping.

These arrived quickly and were packaged well. I like that there are several sizes. I was able to try out several and find the best fit. They are soft and insert into the flange easily. They pop out easy enough to wash also. Not sure about longevity, but so far they seem sturdy enough to last a while.
