Finally a fit, and a Quality Made Product
First of all, I just want to say, the product (Maymom made 21mm one-piece breastshield) is quality made, and I have been using it for the past three weeks. No more pains! Ya. I expressed at least 1 oz more milk every session after I have used these 21 mm breastshields. This one piece product works as well as the two piece Medela PersonalFit 21mm one. What I would like to share more is how I came to this product. Like everyone else, I tried the 24 mm breastshield that came with the machine. As a first-time mother, I thought having some pains after a pumping session is normal. I was wrong. After few days of using it, the pains were terrible. I experienced a lot of pains and bruising from using the standard 24mm shields. From the diagrams on Medela's website and the information that comes with the pump, the flange should fit with just your nipple being pulled in during pumping. It is confusing if you have a mixed areola/nipple area. The problem is that my 'areola' protrudes about 1/8 inches and I thought that is part of the 'nipple' area when I talked to a lactation consultant. The lactation consultant told me to try larger breastshields. I tried larger one (27 mm), though it did not hurt as much, my milk supply went down by one-third and the bruise area became large. I felt every suction along the pumping. I tried the next size up - 30 mm, even worse! After reading more and more reviews, I decided to try a smaller one. I ordered both Medela's PersonalFit 21 mm breastshield and this Maymom made one (it is cheaper, and others said it is easier to clean). Tada.. No more pains. Both brands worked well. Finally a FIT. I realized now that when I was using the larger ones (27 mm and 30 mm), it was more of the 'areola' that was pulled into the tunnel and the milk ducts were blocked during a suction action. Therefore, less milk supply. When I was using the medium one, the sensitive area of my 'areola' was rubbing the tunnel, thus pains. So the bottom line - know what are the nipple and areola of your breasts. It is the nipple part that should go into the breastshield tunnels, not the areola. Choose the right size and pumping will no longer be painful!

Great set at a nice price
This is s great kit at a fair price. Thanks for making quality, affordable items for pumping moms. I keep a pair at work, and one at home to avoid accidentally forgetting them. So I am happy to have found these. I like that they have different sizes because we are not all made alike. I would recommend the Cloth Diaper Wet and Dry Bags by Zhiyouju to keep these in. And while I'm at it, here are a few tidbits fit first-timers since I'm on year 10 and child #4 of pumping. -As mentioned, keep a pair of everything at home and one at work. I realize not everyone has the privilege of a pump at work. In that case, keep the pump at work and learn to hand express at home. Unless you are REALLY good at remembering things. Because nothing is worse than getting to work and realizing you forgot your pump or supplies. -Get bottles that are compatible with the pump. Dr brown bottles will twist on to these shields. You'll save time and energy by not having to pump into bottles, transfer, and wash. -Store parts in the fridge between pump sessions so you don't have to wash them. Believe me, any bit of time you can save to get back to work week be great. -And finally, drink water, take fenugreek, and pump often. Start pumping before you go back to work. Freeze it. It won't go bad. You're awesome for breastfeeding and even awesomer for pumping. It's not an easy job. Kudos!

Highly recommend! Fits madela Instyle pump parts perfectly
This should be the standard issued size with your pump! there is little to no info given on breast shield sizes when your starting your journey to breastfeeding and pumping, and having this little piece of info can be a game changer! I was issued my Madela Instyle Advance pump with 24cm shields, and they were so large I had my whole( small b cup) boob basically squeezing into that thing and losing suction the whole time, having to hold them on to pump anything at all, all the while not knowing any better that it shouldn't be like that, you shouldn't have that much in there, and you shouldn't be in pain. This made ALL THE DIFFERENCE! I actually have milk pumping properly and in abundant amounts, I'm not in pain, and not having to hold onto them the whole time, which was the huge thing. Ladies, if you have small breasts, see if you have the right size shield. Also try a pumping bra that's not the strapless zipper one from madela. I bought the hofish brand two pack for $25 here on Amazon and it also made a huge difference! I wasn't constantly pulling it up because of my small chest making the strapless madela one roll downward. They are optional strapless too, but adjustable in the back so it isn't a crappy zipper that breaks every month or so. purchasing these shields changed my entire perspective on pumping and my whole experience with nursing too. I increased my breastmilk supply having been able to pump properly when needed, and express what I needed when baby was done nursing. Seriously look at the shield size chart from madela, I never knew it existed until I saw these online and looking on Pinterest I found the chart.

A smaller size makes a huge difference
In terms of options, Maymom offers an exceptional assortment of flanges - much more than Medela, which is somewhat sad since Medela offers so many breastfeeding products. I never thought I was going to need the smallest shield that is made. Indeed, I went through bigger sizes - since many women need larger sizes rather than smaller sizes - before realizing Maymom had a handy dandy chart. I actually need a 17 mm flange, which doesn't appear to exist. Despite my true sizing need, the 19 mm has done wonders in terms of alleviating pains. The suction caused by a hands free pumping bra makes it vital to get a good fitting flange. Don't just stick with the 24 mm because it could lead to blisters and days of misery. Ultimately, these shields work pretty well. I like the one piece function for the stability it provides. When I am removing the flanges from my hands free bra, I don't want pieces to disconnect - it happened to me with the multi-piece Medela flanges and milk went everywhere. The single piece, however, can make cleaning more difficult. The shields are made of the same hard plastic as the Medela shields. In addition to an even smaller size, I wish Maymom would look into flexible flanges or angled flanges (kind of like Pumpin Pals but in a smaller size). I guess Medela once made soft plastic flanges but they were pulled. I urge you to consider this company for your pumping supply needs. I'm appreciative that I can get supplies quickly. I've tried tubing from this company, and it actually has worked better than the Medela tubing that came with my pump. The valves and membranes are also equal in quality to the Medela pieces.

Don't let the bad reviews deter you
These are great, as long as you know what you are ordering. I almost didn't order because of some other reviews, so here is my main takeaway when considering the negative reviews. 1. These aren't medela parts. Ultimately, I don't see why you should care because they work with the medela pump and you can't tell a difference. I got the smaller medela shields and use those half the time, and there is no difference in output. 2. These are one piece. A lot of people complained about not being able to get these clean. Maybe they have changed the shape since those people ordered, because these are just as easy to clean as any two-piece shield. In particular, some people complained that water got into a sealed chamber and couldn't be dried out. As far as I can tell, there isn't a single part of this that is sealed off. Water goes through it all and always comes out the other side. 3. Use with a hands-free bra: Ok, I will admit it is harder to use my Lansinoh hands-free bra with these because you have to shove the entire back end through the openings, but seriously, that takes about 10 seconds longer than assembling the two-piece shields through the openings. Maybe the people who complained have a different type of bra. I usually use this to pump when my husband is taking care of the baby and use my medela shields when I have him just because when he starts screaming that extra 10 seconds can seem like an eternity, but if I forgot to wash my other parts and these are clean, I use these and don't have a problem. The only thing I would say about these is that I feel like it is easier to spill if you bend over than with the medela two-piece shields. I lost a lot of pumped milk the first week that I had these, but once I figured out where the tipping point was, I have had no further problems.

superior to the medela flanges, size is perfect for me
I have been using the standard medley pump flanges for a few years with my first son and now with my second. I used to get bruises and have lots of pain when I used these... I didn't know the flanges came in other sizes. I know I have very small nipples and I didn't realize that the pump was actually taking in tissue it wasn't supposed to suck in. I honestly just thought to look into alternative pump flanges a month after my second son was born and I did it because the end of the areola and nipple never felt drained, when I self expressed, I always got another let down and it was back on with the pump flange. So I decided to get the smallest flange out there and I am so glad I did! these 19mm openings produce more let downs, my nipples aren't misshapen afterward and they no longer bruise or hurt. I think the design is similar but improved upon the original flanges in a way that minimizes spray in the vertical chamber which reduces waste...for those of us who try to recover every last drop. The perfect way the milk falls from its intended port into the second chamber is so much more direct and as the design has intended it compared to the other flanges. I don't like 2 things, the opacity of the thicker plastic nipple chamber makes visibility difficult. I use compressions in conjunction with each let down and in between them so I do watch for visual confirmation in the chamber. However, the thickness of the chamber surrounding plastic is an improvement over the other flanges...I actually have a crack in one of the first flanges I used in the chamber which could have soon spread and compromised its suction. The overall construction of these flanges is superior and improved. Everything fits very snugly where parts are meant to be attached. The second thing I don't like is that these flanges are smaller and aren't as secure in my hands free pumping bra with round holes (not the type with overlapping material) as the larger, original flanges...the holes in the bra are somewhat stretched and if I compress during pumping, the bottom of the flanges can pop out of the hole. This too has an upside...i am able to compress more breast tissue without the larger perimeter of the other flanges...so I can just get another bra or modify this one. And, the diameter, of course, is perfect for me. I think this company has made a superior product both in design and function...they offer a size medley does not and it's exactly what I needed. It's a well priced product...they seem well worth the price and I would have paid more for these after knowing what I know about them now. I highly recommend trying a smaller flange if you experience bruising or have build up of milk in your nipple that isn't adequately removed while pumping.

Difficult to use with medela hands free pumping bra
When these first arrived I was happy to see less pieces than the original parts that came with my pump- less parts to keep track of seemed like a good thing to me. However I realized that this was a problem once I went to actually use them. I have the hands free pumping bra by medela and have been very happy with it, but it is very difficult to use with these one piece components. This is because the openings in this bra for the pump parts to fit through are very small (I feel that this helps get good positioning and suction). With the original ikon parts you can easily slide the neck through the small opening and then connect the second piece. With the one piece design it is very difficult to slide the whole piece through the small opening. If you are planning to use with a medela hands free pumping bra beware, if you are planning to use with another hands free pumping bra, I believe you will be happy with the purchase.

Hard to find size locally but this one is perfect!
I am so thankful to have found this size breast flange on Amazon! When you pregnant the last thing you expect is that things will go wrong. Sure the idea is in the back of your mind but you push it away. This might be why I was caught so off guard when our newest little bundle of joy was born 5 weeks early. So many things were a challenge, including eating for her. I found myself pumping what seemed like all day and night. I wasn't getting much milk for her and we had to use formula for many reasons including her blood sugar as I was diabetic. We spoke to experts on lactation and when all was said and done, I was still on the pump trying all I could to get as much milk for baby as I could. One suggestion that came my way on a specially difficult low supply day was trying a smaller flange. My husband and I and baby plus our 5 year old set out into the big city in search of what we knew existed. 5 stores later, we came up short and I found myself in pain having over done it and with 2 little girls who just wanted to be home. No smaller 21mm flanges. Why had babies r us and so many other stores failed me? They had larger sizes but not smaller. Amazon though didn't disappoint. I ordered on here from Maymom and in 2 days I got my flanges. 21mm as promised, clean well made plastic flanges. They are perfection and fit perfectly with the medela bottles I have, the tubing, and on two different pump in style medela machines! I am so very thankful! Now I am working on seeing if these give me more or less when it comes to output of breast milk. Wish us luck!

Excellent product, definite recommendation
I am so glad that I decided to order these. I was a little hesitant at first because they were not from Medela. Sadly, Medela doesn’t make a 19mm flange but that doesn’t matter. This one is so effect. It works great with my Medela Symphony. Now that I have the proper flange my output is way better. Totally worth it. I would definitely recommend!

Passen sehr gut zu Medela Pumpen.
Funktioniert sehr gut an der Medela Symphony, nur an der Medela Swing Maxi (für zwei Brüste gleichzeitig) muss man am Luftschlauch basteln. Aber das liegt nicht an den Brustaufsätzen sondern an den Schläuchen der Swing Maxi. Gutes Produkt!

Got the Job Done
Easy to figure out how to attach to put parts together and connect to medela pump. All attachment parts are sterilizable too, however you may need a smaller brush to scrub inside of the valve for proper cleaning.
