Maymom Breast Pump Kit Compatible with Medela Pump in Style Advanced Breast Pumps;2 Breastshields (one-piece, 24mm), 4 Valve, 6 Membrane, & 2 Pump-in-Style Tubing Can Replace Medela Pumpin Style Valve

Using these with my Spectra pump and the maymom Flange adapters, takes advantage of the superior pump of Spectra. These are great, Maymom products are very affordable and all components fit together well.Spectra vs Medela pump in stylebackground: breastfed and pumped for 2 children each for a year with Medela pump in style with no real issues, though the milk filling the tubing was annoying and the valve membranes wore out every now and then and tubing had to be replaced a few times. With #3 learned about the Spectra from people at work and since insurance would cover it I received from them. I've now been using an old Medela and the Spectra with the new baby and have these pros and cons to share.Medela pros:- valves work better (though they are flimsy and membranes need to be replaced sometimes they provide a much better seal)- adjustment is incremental (not leveled)Cons:- tubing gets gross when milk gets into it- missing some of the cool features of spectraSpectraPros:- backflow protector so tubes always are clean- light for pumping at night or in dark room- timer (very helpful for me so I don't zone out and accidentally pump for 30 mins)- more different types of adjustments that you can play with (this could also be seen as a con depending on your perspective)- "hospital grade" pump- very very quiet (much quieter than the medela)Cons- valves seem to not work as well as the medela- bottle flange doesn't fit standard bottles (like dr. browns)- jumps in the levels can be a bit intense, I've worked up to L5, but I find it hard to handle sometimes, though the higher levels do get more milk faster- The very slight incremental adjustments of the medela are easier- coordinating the cycle length and levels can be a little harder to manage than the simpler adjustments of the medela.Adjustments:I've played around with different configurations, I am now using the Maymom medela valves on the spectra flanges, I plan to get the maymom flange adapter connector piece so that I can use the Medela flanges with the spectra pump. When I use the medela valves on the spectra I get between 1-2 ounces more in a short session 6-7 minutes!If you go with the Medela (which is still a fine option, and worked for me for two years without issue) I would get the spectra backflow protectors to avoid the tubing getting filled with milk, also just plan on buying some more valves.With a smartphone you can mimic some of the features of the spectra there's a great free app "babynursing" to help with timing of breastfeeding sessions and pumping, and a flashlight on the phone can be helpful at night.Good luck!

I got a set of these and was having problems with the suction so I contacted customer service with my questions and complaints. I was originally concerned with the fit. They got right back to me saying that there may be a problem with the product since the suction shouldn't be a problem, so they asked for the special item production date which was on the horn part. I gave that number to them and the said that they would ship me another set in the same size to try as well as the 19" 24" and the 22" inserts. I couldn't believe how fast and personal the responses were. I'm talking like responding at 2:00 in the morning to my emails back and forth! They are based over seas but have a local branch here in North Carolina which is nice for contacting purposes.The new product worked perfectly.I even did some research on the company and the testing they did on there products they went through to pass FDA guidelines since the provide copies of the tests on their website. Everything checked out as being legit and official. This a a great new company producing a highly affordable quality product with wonderful customer service. Buy this instead of the name brand. If you have a problem with fit or quality contact them and they will be sure to make you happy!!!

What a great company to order from! They stand behind their products, and promptly answer any questions/issues you have about their products. They may be a young company, but they have far surpassed most established companies in customer service.I had no idea that the shield/flanges came in different sizes other than the standard 26mm that Medela issues with its pumps. I also didn't realize that the sore, tender, redness I was experiencing was abnormal and meant I was using the wrong size.Enter Maymom.I ordered the 19mm set and they are amazing! No more prolonged redness after pumping, no more sore, tender nips. I can pump the same amount of milk in almost half the time! I am beyond happy with my purchase. So happy that I purchased an extra set of shield/flanges so I had a spare in between washings or to keep at work.If you're going to be a pumping mama, do yourself a favor and measure your nips. I'm telling you, this will make such a difference in your pumping experience!And as an added bonus, there's one less piece to keep track of. The shield is one piece-and I had no issues cleaning it compared to the standard two piece offered by Medela. I also boil water and put them in the sink with soap to soak/sterilize, so I haven't had any issues with cleaning.Also, they fit just fine in a hands free pumping bra....which I didn't really think was a necessity at first, but it really is oh so worth it if you're pumping regularly!

I wasn’t sure what to expect when I bought this product vs going the more expensive route of buying replacement parts from Medela. I am so happy I tried it! All parts came in great condition and with helpful instructions on how to assemble and clean. The quality of the plastic is just as good as the Medela ones. I actually like that the shield and bottle connector are one piece- less parts to have to deal with! I just use my bottle brush to get into the longer legs and it cleans up nicely. Each piece seems to work well interchangeably with the Medela pump parts, so it isn’t like I have to use them all together. I’ve tried mixing and matching, including the tubes, and seem to pump the same amount of milk. Definitely recommend if you are on a budget and need doubles, or triples, of parts for work or just so you don’t have to wash parts after each pump session.
