Can beat the price
I needed new duckbill valves and ordered these in a pinch. They arrived quickly and do a great job for my pumping journey.

**I thought my pump was broken*
These work like a charm! I thought my pumps were broken but realized there was a small slit in the internal pump part. If your pump tune is sucking, but milk is not coming out, check the internal white part. I ordered this set immediately. I appreciate that they are universal parts and easy to use. Great price for this entire set!!

Works great with spectra
I have the blue spectra and the pink Spectra, recommend highly for part replacements for either of these pumps. I pumped heavily for both my kids and had to replace parts when my supply started dropping. These were great.

Quality product for a great price!
Highly recommend buying this pack! These work seamlessly with the spectra synergy gold breast pump and work just as well as the name brand version. They are well made and for a great price. Don’t spend more than you need to!

Love
This was such a great asset to my pumping routine. It has helped me with time as if one set gets dirty I already have another clean set to use

Doesn’t last as long as brand name
The small pieces don’t last as long as name brand (you’re supposed to replace when you see any separation) but this is a wonderful solution that is a fraction of the price of name brand. Works just as well!
Chantel –
The duckbills work alright, but the backflow protectors don’t close together very well and so the back piece that attaches to the tubing pops off a lot.
sal –
The backflow protectors pop apart easily, meaning that I’ve had to hold them together in order to pump. Extremely inconvenient, as it eliminates the possibility of hands-free pumping.
