Review on Upgrade Your Spectra Pump: Nenesupply Tubing - Compatible With Ameda And Avent - Replace Your Spectra Accessories by Andre Hawkins

These are excellent. I like the extra room the longer tubing gives me since I exclusively pump. I am able to more comfortably hold my daughter while pumping since I can run tye tubing behind my back.But the real star of the show here are the valves. From first use of the original Spectea valves I noticed the suction just wasn't that powerful. I almost returned the pump because I was not happy with my output. But I put these valves on and WHAM! Better suction and better yield. I will be order more of these valves :)
