**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!!

Nearly Identical to Original Pieces
So far, so good! I found myself in quite the dilemma when one of my original backflow protector pieces cracked, so I ordered the fastest replacement I could get my hands on. I have the Spectra s2, and these pieces fit perfectly. Both the duckbill valves and backflow protectors look and feel nearly identical to the ones that came with my pump. I haven’t seen any change in output either! I will update if anything changes, but I don’t foresee that happening, thankfully!

Backflow protectors don’t seal well
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.

Very handy
These are great and handy to have the backflow protectors as spares when my others are dirty, the valves are also of great quality.

Loss of suction
Half of the duck bills in the pack don’t work as they should. I will try a new pack to see if any better and adjust my review accordingly as might be a defective batch. Valve works great though!
