"I was given this product to try as part of the weeSpring Parent Panel and I am so happy that I was. I am not a fan of the whole pumping process and these flanges took the chore of pumping and made it bearable. I found the flanges a lot more comfortable than the standard ones that are provided with your pump (I have a Medela In Style). I also liked that it caused a lot less friction so I was able to pump more comfortably for longer periods or time -- TOTAL PLUS! The only thing I do wish is that these flanges allowed you to relax a bit more, but sitting upright for this level of comfort was totally worth it. I would definitely recommend,"
