Silicone Flange Inserts 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps Compatible with Momcozy, Lansinoh, Elvie, Willow go, Spectra, Breast Pump Shields (10PCS)

Needed for more breast pumps, easy to find your size

I've been using my pumps for maybe a month, and really struggling at times to get decent suction. I'd been wondering why and trying to figure it out. I had initially sized my nipples with a generic sizer, the card with holes cut out, and thought I was using the correct flange size. I got sick of struggling to get suction, so decided to see if it was a size issue, so I gave these a try. Long story short, great product so far, easy to use, good quality and work great with my Momcozy S12. They have definitely improved suction and as such I hope will improve output.

As described, I love these inserts I use these in my Momcozys ( s12 and M9) and I use in my eufy as well. Good value for money

Sizing gauge is very useful and flange works well in Medela hand pump. However, tried it in my Elvie pump and unable to get any suction at all unfortunately. Still worth a purchase to get size right and useful for when I have the available hands to use the hand pump though!

I should have known these wouldn't be any good with how cheap they were but you learn as you go on your first baby! Tried both sizes that I take in other flanges and they were so tight with my pump and hurt when pumping so they went straight in the bin.

These inserts saved me. They work well with the Elvie and have made pumping immediately much more comfortable. The sizing tool is really helpful (I realized I needed different sizes on each side!) and the inserts are easy to use.

Very unfortunate that pumps, even the costly ones, often don't come with varying sizes of flanges! Nickel and diming new parents! In midst of that, this was a very effective cost saver. One thing to be noted is - the quality could be better. Quality of what you get from original manufacturer is better, but does that impact the usage of pump - NO! Which is why I give this a 5 star!

Allowed me to continue using a breast pump without pain. Sizing guide included to make sure you're using the right flange and fits perfectly into my breast pump

Nickel ! Je les ai achetées pour mon tire-lait Lulia !
