NENESUPPLYPump Parts with 19mm Flanges Compatible with Medela Pump in Style Maxflow Breastpump and Personalfit Flex. Incl. Flange Membrane Connector Tubing Valve. Not Original Medela Pump Parts

My wife felt so much relief having a pump size that actually fit. It works well and she got more milk out using these.

These pump parts are amazing! I originally have the medela pump in style with max flow and the main pump parts are not the best when it comes to leaks! If it turns to the side any direction my milk leaks out and if for those that exclusively pump this is a devastating occurrence. Every drop is so precious and any milk spilt is such a loss especially when your working so hard to make milk for your little one. That being said these pump parts have leak protection and if you turn or bend in any direction you are good! Easy to clean and small and compact compared to other pump parts. Highly recommend and I hope this helps.

I was hesitant to try these but the price was right. They do work well and my milk has not had a decrease in amount. They are easy to clean and have held up well.

I'm 5 weeks into exclusive pumping, and realized pretty quickly I'll need extra sets of parts, since I'm pumping 7-9x/day. These work better than the set that came with the Medela pump in style... more milk production, less bulky, and they don't spill out if I bend over to reach my baby. Only downside is they have more and smaller parts to clean, but it's worth it to me. These aren't my "spares", I'm using them over the name brand now.

I ordered this as a backup for my madela pump but it didn’t meet my hopes for a few reasons:1. The tubing is smaller than the standard one and the attachments are not interchangeable with the tubing included with the pump.2. The seal on the joint piece didn’t seem to fit tightly and seemed to allow for air to get in reducing the suction power3. The flanges were perfectly circular and personally didn’t fit well on my breasts. Milk seemed to leak from underneath when used and the stem of the flange was very straight causing me to have to lean forward to avoid any more leakage4. No returns. Upon opening the package and before use I knew it wasn’t what I was looking for and was prepared to return it to order what I needed and wasn’t able to.

Definitely way better than my Medela attachments that came with my pump.

It's not easy to wash. You need very thin bendable brush. Fortunately I already had it. Without that cleaning is troublesome.

I have the pump-in-style and these pump connectors are 1000x better than the ones that come with the pump. They are more efficient in emptying the breast, more comfortable, less bulky, easier to clean, and for those ladies who are low suppliers their is no lost milk in the connectors. Where as I was finding I was losing 1/2 oz each in the Medela brand due to poor design.Go buy this connector!

The flanges are really hard plastic and not that comfortable but the suction is great.

useless dont bother
