### ⭐⭐⭐⭐⭐ Do not sterlize this

### ⭐⭐⭐⭐⭐ Life saver
*by A***R on 10 February 2026*

Works perfectly for my spectra. I thought my pump wasn’t working until I realized I needed to replace the parts

### ⭐⭐⭐⭐⭐ Works like the original part
*by K***M on 21 March 2025*

I've had problems before when ordering replacement parts for my breast pump. For some reason, they can be slightly different from the original version, which means the parts don't fit together right or the pump doesn't work as well. Happily, this backflow protector worked just as well as the original parts. (I had to replace the previous part when it got mold inside that I couldn't scrub off.) It fits, and works perfectly well.
