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)

Great product! Plenty of different sizes, comfortable and easy to clean!

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.

They serve the purpose well.

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.

This flange is too long for using with Momcozy pumps. I used it and it broke my pump. It covered the hole where the milk is sucked into the pump and then filled up the suction area and into the hole entrance for the motor. When I realised this it was too late. The motor would not switch off and the mode and level function would not work.I am devastated as the Momcozy pump was expensive

They do exactly what they say. good price and happy with these and would definitely buy them again

Worked perfect with my wife’s Medela hand pump and Ardon electric pump.

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
