Nuliie10PCS Flange Sizing Kit 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps, Silicone Flanges Insert for Momcozy/Spectra Electric Breast Pumps, Pumping Essential Kit for Moms

Summary: it’s exactly as advertised. You get a variety of flange inserts to test, a very handy brush to wash them, and a nipple guide to measure. Easy, straightforward, can’t go wrong buying the variety pack.More detail: it’s packaged well, each set of flange inserts comes in its own plastic packaging in the box. On each insert, the size is printed on the rim of it, so it’s fairly easy to see what size you’re working with.The included brush makes it much easier to clean, especially if you get bits of milk stuck around the edges, which is pretty common for me. It’s difficult to get it fully clean when using a traditional bottle brush, but the included brush is made of a soft material that really gets the milk off.It fit perfectly in my spectra flanges, and fit pretty decently in my Mandela ones- it just needed a little bit more finagling to get a flush fit.This was a good way to test out a variety of different sizes quickly.Tip: the silicone can stick a little, and create friction on your sensitive areas. A dab of coconut oil on your nipples before you pump, and you won’t have this problem.You can also apply the oil directly to the flange insert, but it gets a bit messy. Putting it on your skin is just as effective, without making the flange overly greasy.

The flanges are of silicone and great quality. You get a pair of each size, a ruler to measure, and a brush to wash. It is compatible with Spectra S2 and Medella manual hand pump. It is packaged really well, with individual packing. The brush is soft and cleans well, hence no scratches either on the flanges. It is a great value of money, since you're getting a variety of flanges in very less cost. The measuring tool is a silicone one as well as a paper on. Unfortunately I was in between sizes, so I contacted customer support and they got back to me with prompt responses. Great customer support, they were very kind to offer me a free replacement of the other sizes. You should go in for this product as it lets you play around with different sizes at a fraction of cost.

These probably aren't the best quality flange inserts you can buy (I wouldn't know for certain as I've never bought any other flange inserts) but when everything else is $12 per pair, the value you get for this sizing set is huge. They fit perfectly in my Baby Buddha flanges and I like that it comes with multiple sizes so you can switch them out as needed. I noticed some other reviews said their kit only came with a paper measuring tool. Mine came with a paper tool plus the silicone one.

This kit was extremely helpful in finding my proper flange size for my breast pump. Once I found the right size, I now place the silicone flange inside the larger plastic 24mm flange that attaches to my breast pump. The seal is great and works perfectly! Easy to clean and sterilize too.

I didn’t realize how much of a difference flange size made until I used this kit. The Nuliie Flange Sizing Kit helped me find the perfect fit and completely changed my pumping experience. Definitely noticed more comfort, better output, and way less frustration. The inserts are soft, high quality, and easy to clean. I use them with my standard 24mm flanges, and they pop right in without any issues. I love that they’re BPA-free and come with a clear nipple ruler for measuring, which made it easy to finally understand what size I actually needed.My only complaint: the inserts come grouped in sets like 13/15/17/19mm, so I didn’t know which set to buy before getting the sizer. I wish I had known to start with the ruler first it would have saved me some trial and error. If you're a pumping mom dealing with pain or low output, this kit is absolutely worth it. Just be sure to measure first.

I've been wanting to get this kit for awhile. The measuring tool is handy and comes with a paper one as well to keep in your bag just in case. Love that it comes with multiple different sizes to get a good fit. The sponge brush is also handy for more than just the inserts!

Absolutely amazing to have during your pumping journey. The sizing pad was very helpful. I have been using the inserts for a few weeks now and still working great!

Flange inserts are awesome for your pumping journey and these ones are great for getting multiple at a great price. However the longevity of their use just isn't there. I've been pumping for 1 month only and already I need to buy a replacement kit because the quality of these flange inserts are poor and they have all lost their "stickiness"
