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

They look and feel slightly different than the s2 tubing that came with the pump but they fit well and work perfectly. they seem to be holding up to use and sterilization rather well.however i find it shady that the manufacturer sends a note with the product that says if you leave them a 5 star review and send them proof that they will paypal you back $2 of your purchase price.update: within a month both tubes started to crack where it mounted to the backflow protector. easily fixed by cutting away the area that was damaged but left a slightly shorter tube. they seem to be working well despite this
