These have worked great for me. I've been able to use them in various pumps and they've definitely done what they're supposed to. It's great that they come with so many because my flange size has changed more than once during my baby's 9 months!

Great kit that includes all the sizes to try. Great for if you’re not sure which exactly you need. This allows you to test and refine the fitment and comfort. My wife has been using these for the past 3 months and with daily cleaning and sanitizing they show no signs of wear.

I have several pumps and of course no pump comes in a one size fits all. This allows me to be comfortable in all of my pumps. Easy to clean. Holds up nicely through sterilization and comfy.

1-A-passend zur Pumpe. Einziges Manko: da sind so viele Flansch in anderen Größen darin. Was mach ich damit??? Besser wäre, in der gebrauchten Größe Einzelpackungen zu verkaufen. Weil ausgemessen hatte ich ja bereits davor (mit der Schablone der Pumpe)

This is an excellent little package, such great value! And how clever to give a variety of sizes along with the measuring kit!! The first time I used this (with my madela flanges and pump) I got nearly twice as much milk! I can't say it was only this item which contributed, as it was also day five of power pumping, and I also added brewers yeast to my diet at the same time as well, but those three things seemed to really help after a month of other less effective attempts at increasing production. And what a neat little bonus brush as well! So much more cost effective and actually helpful compared to the various other items which I've tried

Honestly these were great! I’ve gotten some in the past and they were pretty flimsy and just didn’t seem to be right or the correct size that was on the flange! I only needed the 19 and luckily it comes with measuring so you can always check to make sure you’re still the same size!

A useul pack for any pumping mum to have. The right flange size is so important for pain free, efficient pumping. Most women do NOT fit the standard 24mm or 28mm flange most pumps come with so measuring is so important to succeed! This set comes with both a cardboard and rubber nipple ruler which is fantastic, I appreciate the rubber ruler so much more as nipples are soft and sensitive and I'm afraid of papercuts with the cardboard ones! I have recommended the same set to my pregnant friends too.

This was purchased for my wife for use with her Spectra S1 Plus. The sizing kit was easy to use and now pumping is much more comfortable. Kits similar to this should absolutely be included with all pumps so that people get the right fit from the start.

This is so smart and a great price. Your nipples change sizes, an insert is cheaper than buying different sized flanges (though you can do that) I also liked the measuring tool-wish I’d known/had these my first time nursing.Super inexpensive way to ensure you’re getting a good fit throughout your pumping journey. Highly recommend! A must have item!

This kit was excellent for providing my daughter with a way of adjusting the flange size of her breast pump which only came with 24mm and 28mm flanges. They seem to be a universal fit and come with a handy nipple measuring guide to help avoid the awful damage that comes from getting the sizing wrong. Really excellent.

These are great for the value! You do not need to spend a lot on flange inserts in my opinion. After using these for a couple months now I’ve learned to use them properly! They are hard to insert and remove but there’s a trick to them. To insert if you bend it and push it in it will help to insert it fully in a lot easier. It’s hard to insert if you just try sticking it in fully. To remove, def stick your finger and bend it then it comes right off. Do not try to remove it by the lips or else it can tear. I dont know if I make any sense but def play around with them. I almost gave up after the first week bc they are a little hard to put in and remove but got the hang of it. Milk residue does stick to it pretty well. If you wash in backing soda it comes right off . My baby dish soap still leaves a residue
