## Customer Reviews

### ⭐⭐⭐⭐⭐ Spectra Compatible!
*by  on Reviewed in the United States May 29, 2026*

Bought these to use with my Spectra S1 and they worked perfectly! Finding affordable and fun (pink!!) replacement parts for your pump is always a win in my book!

### ⭐⭐⭐⭐⭐ Wonderful
*by  on Reviewed in the United States May 17, 2026*

Works great with my spectra!

### ⭐⭐⭐⭐⭐ Great Affordable Alternative to Brand Name Parts
*by  on Reviewed in the United States March 30, 2026*

These replacement duckbill valves are great. They were delivered quickly and are a very cost-effective option compared to the brand name parts.They function just the same as far as I can tell in terms of output, so I have not noticed any difference at all when using them.I also really like that they come in different colors. It makes it easy to keep track of which parts have been replaced and which ones still need to be, which is super helpful when rotating pieces. Overall, a great value and I would definitely purchase again.
