A lot of size options.

Worth the purchase
Excellent quality and great fit for my portable pump. Increase my milk supply due to having improper fitting when pumping.

Inexpensive and efficient
I've used these with multiple different pumps. Very versatile and works as expected. Included sizing tool was extremely helpful in determining size needed

Works
Very convenient for pumping, down side would be that they feel just a tad loose when inserted but they get the job done

Didn’t Come with Case Pictured
The item itself works fine but I bought this specific brand for the carrying case that appears in the review pictures. Mine did not come with a carrying case, all the parts were just loose in a box. I probably would’ve gone with a different brand had I known.

Must have Postpartum
These helped me tremendously. I was not getting much output before ordering these. Got my correct size and was able to test them out and got much more milk out!!
