10pcs Pump Parts Set, 2pc Backflow Protector 2pcs Tubing 2pcs Membrane and 4pcs Duckbill Valves, Replacement Breast Pump Parts for Spectra S1/S2/9 Plus

Came in exactly as described. Works just like the pieces that came with the machine.

Great cups used them in the car, at home, work, cheesecake factory, lol basically everywhere even Disney. Would just recommend to bring extra clothes just in case you don’t seal it correctly and it spills all over you it happened more than once so yeah make sure to seal it well and just keep clothes in the car just in case. But it’s great easy to clean and durable. The pour is so satisfying too.

As an over producer and a person that hates wearing pumping bras, I was really excited for these. I use a different brand collection cup and wanted a 2nd, more affordable set. I liked the overall design. However, it was poorly made. The built in back flow protector/diaphragm was great and easy to assemble. However, I made sure to very carefully ensure the silicone flange was fitted around the edge of the collection cup. Long story short i reached into my fridge to grab something and ended up wearing 9 ounces of milk. The WHOLE bottom of both cups completely slipped off. Now I’m scared to ever use these again. I KNOW I put them together correctly because it was the 4th or 5th time I had used them.

Bought these as replacement and fit my Brest bump perfectly

First let me start off my saying these for great and are comfortable. I like the fact it comes with different flange sizes for a customized fit without having to buy another product. First issue is they leak way too easily. I’ve never lost so much milk because the bottom popped open, even after triple checking it’s secured. Second, I use these primarily with my Spectra (what it’s “compatible with”) but the tubes keeps falling out.

The backflow protector has a tendency to make a weird clicking noise during pumping but doesn't always make the weird noise. The tubing is a lot softer so it makes plugging into the pump and backflow protector a little more difficult. The duckbills are similar to the original and are okay. Overall a cheap set and not terribly expensive when compared to the Premium Accessories Kit (which does include a bottle and flange over this kit but still doesn't explain how it would cost 3x) I would recommend this kit due to its price when compared to the official speCtra kit

was really looking for something affordable and fast. i usually only get an ounce from my left side and feel so full after a pump. After using this cup i have never felt so empty. as an exclusive pumper i love these. and i saved some money. 10/10 the only thing is i had remove the tubing from my original pump luckily they provide tubing and an option of flanges... more than i have gotten with my expensive pumps.

Great quality pump parts will buy again with next baby
