"Best I’ve Used. I tried many different collection cups in search for a hands-free pumping experience. This is my favorite because it does not leak and has the highest capacity. I was finally able to walk around while pumping. These cups are well made and the parts assemble easily. Get these if you are in the market for pumping collection cups."

"I love that it came with two different sizes of flanges! Hands-Free, I just put them in my bra and it holds them. I really like that they have oz and ml measurements on them. Makes it easy to keep up with how much milk I am producing."
