Review on Nenesupply Pump Parts Compatible With Medela Breastpump Not Original Medela Pump Parts 24Mm Breastshield Valve Membrane For Medela Pump In Style Medela Symphony Swing Replace Medela Breastshield by James Prizgint

These are not the same as Medela. As soon as I took them out of the package, I put them right back for return. While the tunnel width is 27mm and the quality appeared to be comparable to Medela, there were several differences that I noticed immediately.1. The tunnel was shorter than the Medela brand2. The width of the dish part of these shields was more like one on the 24mm shields.It's #2 that made me stop and take notice. The width is important because it's meant to cover the areola. If they aren't wide enough, it can be uncomfortable. There is a reason that the size of the dish parts increase with the size of the tunnel.I posted two photos to show the comparison. This brand is on the left (still in the package) and Medela 27mm shields are on the right.
