## Customer Reviews

### ⭐⭐⭐⭐⭐ Must have as a breastfeeding/pumping mom
*by A***L on July 25, 2025*

As a second time mom I highly suggest this product if you plan on pumping it will help you get an idea of what size flanges & inserts you need for a perfect fit. Keeping in mind your size fluctuates from time to time so it’s best to get a pack of pump inserts in a range of sizes bigger and smaller than your measurement so you can see what works best

### ⭐⭐⭐⭐⭐ Compatible with spectra and lanisoh
*by G***R on July 9, 2025*

The 21mm Works well with Spectra 24mm and lanisoh 25mm flanges

### ⭐⭐⭐⭐⭐ Amazing BUT…
*by K***E on August 7, 2024*

They get 5stars because they saved my poor nips and that’s worth a lot. So I have now bought 6 sets of these which 5 oh were EXACTLY as described and work super great all sizes were there. Well one of the packs which happened to have 3 of 1 size and only 1 of another which happened to be the size I need, so that’s a bit frustrating but like I said the other 5 I bought were exactly as described so just make sure you make sure all sizes are accounted for in pairs.
