Love that there’s a variety
Love the price of this definitely helped when it came to me measuring my flan size and made pumping so much easier. Especially love that. It comes with the cleaning tool and a bunch of different sizes and that the measuring tool is a silicone base.

Needed for help
I needed these because i wasnt sire what size i was for any of my pumps. I had assumed and was wrong. These have instructions that explain much needed info as well as comfort. It is amazing the difference it made. It was well wortg the money and will recommend and buy again. The ruler is flexible for easy and more accurate fitting. Love it.

Decent!
Love the sizing chart being silicon so it’s not as prone to rips or tears. Quality inserts with a wide variety. They aren’t the most comfortable, they tend to feel a little pinchy but I also don’t use any kind of nipple cream so that would be a must with these! Come with the cleaning brush which is super convenient

Every pumping person should have!
Love the reusable ruler, as size can change during your pumping journey! The little bottle sponge was a lovely addition, and perfect for cleaning the bottle nipples. Every pumping person should have a flange sizing and insert kit.

Great Variety and Handy Extras
I was really impressed with these flanges! They came in a bunch of different sizes, which made it easy to find the perfect fit. I also appreciated that they included a measuring tool to help figure out which size I needed—super helpful for someone unsure where to start. Plus, the cleaning brush was a thoughtful addition and made cleanup simple. Overall, great quality and a very convenient set!

Different shaped inserts
The sizes 21, 19 & 17 are different shapes than 15&13. The larger inserts don’t fit well inside the medela hand pump, which is what I bought the inserts for. The shape of the smaller inserts allows for an easier fit

After using the wrong flang size and wondering why pumping was causing pain this was a life saver. The measurements are spot on and the adjusters fitted right into my current pump. Huge difference in comfort and milk output.

Would recommend to anyone pumping, standard flanges on breast pumps are way too big and stopped me from pumping. Would have pumped more if I'd had these from the beginning. The nipple measurement guide really helps with gauging size. Easy to clean, I washed with hot soapy water and threw in the steriliser.

Sizing tool is helpful and the flanges are working well and are comfortable.
