Maymom17mm Flange Inserts (Long) Compatible with 24mm Medela PersonalFit Flange, Spectra Flange, 25mm Freemie Flange(Restricted Freemie Cups), Compatible with Momcozy 24mm Cup (S9, S10, S12)

I was able to use this flange insert not only with my Freemie cups, but also with my Willow 2.0 24mm Flange.Freemie SystemThe fit with the Freemie cups is incredibly sturdy. It was difficult to get out at first, but after I knew to twist instead of pull, dismantling and washing was a breeze.Willow PumpThese fit into the 24mm flange loosely. I don't think it affected the suction despite the looseness. I just had to get used to holding in the flange insert when I went to take out the milk bag from the unit, so the flange insert wouldn't fall to the floor. Otherwise this made pumping with my willow significantly more comfortable and increased when using the Willow.

I love these. If i didn't have them I know Id hate my Freemies. With my 20 month old I had two pairs of the Maymom 17" flanges. I was a little sad about the Freemie size because the reviews struck me as user error and sizing issue. I took the chance and order those and these... match made in heaven. They make my life easy. I can multitask and pump.To clean them I have to wedge my finger in between the pump and these and I use a chopstick at the else where the little halfmoon hole is to push it out. You must break the seal first with your finger or they they aren't coming out. Easy enough. Easy enough.

I used these flange inserts for my Freemie closed collection cup system. They fit in REALLY nice and tight. In order to clean them out well, you have to remove them each time which is somewhat of a pain. However, this is to be expected for a tight fit. I found that using the nipple brush in the base of the Munchkin bottle brush (the one with the silicone nipple brush that stores in the handle) to pop them out before cleaning was WAY easier on my hands. I sanitized them each time with steam and they held up well. I would recommend these.

Love maymom products so still giving a 4. These long inserts does not work for v1 pro unfortunately. It restricts the diaphragm and affects output.

I have gone through so many sizes trying to find the right size and sure enough these were it! You do have to to make sure the inserts are pushed in nicely and the edges are sealed to maintain the proper suction, but it’s so easy to use! Also very easy to clean which is very handy when having a newborn. I would purchase a back up set because I love these so much.

The media could not be loaded. This is a life saver! My nipples don’t hurt anymore when pumping. It fits well in my freemie independence pump. It is easy to remove unlike the other reviews are saying. Just push it gently and it will come out. The only thing i notice, the suction is not too good. It decreased my milk output when i pumped unlike before when I was not using the inserts.

I RECOMMEND THESE! I love Medela, I’ve had three of their PISAs and one harmony as well as other products they make, but I’ve struggled with their Flange sizes. They only go down to a 21mm and that is still way too big for me. I scoured the internet and found these inserts, oh my goodness are they amazing. The first time I tried them I was very impressed. I didn’t experience any pain and I pumped 2oz in less than 5 minutes with my harmony manual pump. So happy

I had heard great things about these inserts so I was kinda disappointed with my experience with them. I ordered 3 sets before I delivered because I used the Willow measuring tool (before I delivered) and thought I needed 17mm size. I ended up measuring with the Maymom ruler after delivery and found I’m actually 15-16mm but I can’t find an insert that size so I went ahead and tried one set of the 17mm anyway with my Willow. The inserts helped pumping be less painful compared to just using the 24mm flange but it was still very uncomfortable and I did not get my normal output. I do have elastic nipples and I don’t know if that makes a difference in comfort or not but I found that pumping with my 21mm Willow containers and the Beaugen cushions a lot more comfortable, also pumping with my 21mm flanges by themselves on my Elvie is more comfortable than using these inserts. I do have the 19mm Spectra flange inserts and have used those comfortably so maybe I’ll just have to return my two extra sets of 17mm inserts to try the 19mm and 21mm sizes.
