Perfect that is all I can say. They work with all different style pumps.

After having mastitis a few times, I realized that my flange size was off. The lactation consultant at my hospital was on maternity leave, so I had to figure out sizing myself. This kit is perfect for this. Pumping has been more comfortable with the insert and my supply has increased. Given many pumps comes standard with a 21 and 24 flange, this is convenient to try out what feels right before committing to a flange size. But really, I’ll just continue to use the insert instead of purchasing extra parts.

If you are having any kind of pain while you are using your breast pump, getting a kit like this is ideal. The Dr.Isla Breast Pump Flange Insert Kit allows for you to test several flanges to find the size that is good for you. Also, it comes with a cleaning sponge that’s useful for more than just your flanges. I use mine on other parts of the breast pump. There is also a sizing card, I found it less than useful as it is made from cardboard and subject to breaking. I had so much pain before using a flange on my pump, this has made things so much easier.

This product was received as part of a promotion. This set is really nice. It comes with a variety pack of flange inserts along with a nipple measuring guide to help you figure out your ideal size. I’ve been told that the correct flange size is key to getting ideal milk output. The sizes this package comes with are: 13 mm, 15 mm, 17 mm, 19 mm, 21 mm & 24 mm. The kit also comes with a bottle brush to clean the flanges & other parts you may have. These flanges may work in some pumps, but some pumps require you to get their flanges, as some are proprietary. This is a great starter guide to make sure you get the correct size!

This looks like a nice pack, but it didn't have as many measurements as another kit so I ended up getting something else
