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!

Great gift for new moms
Super helpful to have as a first time mom who is new to the pumping world. I would’ve never guessed that you had to size the flanges and it wasn’t just a one size fits all situation. The flange inserts are very comfortable and easy to wash as well as the little brush that comes with is very helpful.

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.

Work well to find out your size. Great for the price.
These work great to get your correct size and pump efficiently, but not a permanent solution. I did use them daily at least 4 times a day for two weeks and then got the flange of the right size to replace these. I ended up using 3 different sizes in those 2 weeks, so these are great to use until you have your final size as your nipple might change sizes. They do work well but they did change color and became less firm the more we put them in the sterilizer. For what I wanted (to have something to use until my final size was conclusive) these worked well.

Not worth price.
Easy to use and find right fit; not worth the amount of money its being sold for. One/two time use.

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.
