It was painfully obvious to me that the breast shield that came with my Medela Pump in Style was seriously too small. I ordered the XL (30 mm) because it was the largest one I found easily. It fit better but still wasn’t quite big enough. I was nervous getting this one since it’s so much bigger than the XL but it fits perfectly! It feels so much better. Plus, I actually get more milk at each session because my nipples aren’t being shoved into a too small shield which can restrict milk flow by putting pressure on your milk ducts. I don’t know what I would have done if I hadn’t found this shield! Shipping was super fast.

I was having troubles pumping and went to see a lactation consultant.She had me pump with the medium size ( 28 mm), then the large ( 30 mm) then the 36 mm.I got the most milk when I used the 36 mm.These shields are expensive and I was lucky enough for the lactation consultant to give me all the sizes to try.My recommendation for anyone buying is to buy a the next bigger size, I think it draws more of the breast tissue in and therefore pumps more out milk.Good luck

Some suggest that the bigger the better, so I got this size. I am a D cup with nursing and a C before. The one that came with my pump seemed way to small, so I got the biggest size based on reviews. It works better, but I’ll have to get a smaller size. Using this size seems to drasticly reduce the amount of suction I get with my manual hand pump. Too bad you can’t just buy one to try it!

Seams like solid manufacturing. I have size H while breastfeeding. I didn’t realize that when you measure your size for this it has absolutely NOTHING to do with you breast size and everything to do with your nipple size. My nipples are pretty big but nothing compared to how HUGE this is. The inside is about the diameter of a quarter.

These were huge but I really needed them for one side that was bigger than the other- these were a lot more comfortable. These still have an angle on the flange that caused me grief though. In the end I was much happier with Pumpin Pals (B0085CBA90and would have saved a lot of money if I had just gotten that set to solve my fit problems in the first place.

I got these under the recommendation of my lactation specialist and I found that when I got the correct size breastsheild, I produced and pumped more milk.I have twins so I pump after each feeding to increase my milk production and not waste any milk… I have 4 pairs as sometimes I don’t have time to wash them after each pumping….Do yourself a favor and get the hands-free pumping bra while you are at it!

Seriously, they need to stop shipping the smallest flanges with pumps! I get a ton of milk with these WITHOUT hurting myself. I needed larger due to my size but these were actually "too big"…I put that in quote because I don;’t think there is such a thing. WIth baby is supposed to latch onto as much areola as possible…then shouldn’t your PUMP do the same?? I also got these for my girlfriend who is substantially smaller than I and what a difference they made for her. Just do it, seriously. They cost NOTHING compared to the pump and what you’re doing for your child is wonderful – give yourself ever opportunity to do it well!

I got these based on another review where a woman claimed she actually got better milk production even though they were bigger. This was not the case for me. They might have been too large for me. They still did do the job and were much more comfortable compared to the standard small size that I was using.

Wish the item was made more similar to standard sizes, just a bit more clunky than necessary to fit the medela pump.

These are the only breastshields that fit me. My only complaint is that the diameter is so large that it barely fits on the medela tunnel so it occasionally pops off if I’m not carefull and I spill all my milk.

They didn’t have is size at babies r us so I had to order it, they’re great. They fit well and they’re comfortable

My wife needs these for her comfort, but they barely fit into the other plastic pieces of the pump kit. Just barely, but they do work.

This is not as big as you think. Thank goodness they make this size! I pump all of my daughter’s milk now and this makes it easier!! Less Pain

Turned out to be way too big (shopping around for the right fit), but they arrived promptly, fit the connectors, and worked as intended.

It’s easy to pump breast milk now. The 36 mm breast sheilds help me much. I can get more breast ilk than before.
