### ⭐⭐⭐⭐⭐ Love these

### ⭐⭐⭐⭐⭐ Great product

Great with Spectra blue. Seems like it bring same amount of milk when I use flange and do hand express.

### ⭐⭐⭐⭐⭐ SO much better than traditional flanges
*by K***T on January 26, 2026*

These collection cups came highly recommended by sooo many mommas (including mybrestfriend IYKYK if you don’t know, check her out she’s the pumping queen) so decided to try them. On Amazon they look like every other “non-name” collection cups, but when I got them I was impressed. The packaging is very well done from the instructions on the box lid to the inserts with sizing info, how to assemble, etc. I purchased the collection kit which came with the cups, a few flange inserts, and tubing that looks like it can be used for the Elvie stride and babybuddha (and any other pump with similar tubing set up). I sanitized/washed them in my Momcozy bottle washer and they fit well—no issues. So far I’ve only used them once for a quick pump with my spectra s1 (blue). The tubes fit on easily and started pumping fairly quickly. I really like the stopper-plug on top so there’s no leaking if you accidentally bend over too far (i.e. picking up a fussy baby). There’s measurements on the side of the cup which is nice. The silicone is soft against the skin and wasn’t annoying. I do think these are less noticeable in the bra than others. I’ve only used them once so far, but I think I like these better than the legendairy milk ones. The nene’s are definitely smaller/less noticeable than the LM cups (also hold less which isn’t an issue for me right now). Overall, with only one use so far, I do think these are worth the current price ($59) in comparison to all the other options on Amazon. There’s only one other no-name set I’ve liked (and are a tad cheaper), but they don’t have the seal on top and protrude slightly farther out from the chest than these nene’s.
