These are great, Maymom products are very affordable and all components fit together well. Spectra vs Medela pump in style background: 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 spectra Spectra Pros: - 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! Review: A perfect, cheaper alternative to the name brand parts - I needed an extra set of tubing due to a friend letting me borrow her pump to leave at work. I looked at various tubing options and decided on buying this product since it didn't cost much more than tubing alone and gave me some extra pieces. Initially I was hesitant because I thought it might be better to go with the "Medela" brand pieces, I was worried about quality with these. Rest assured, these are just as good! Tubing: The tubing is identical, except the cream colored part is a VERY slightly different shade of cream. No big deal. I ran some water through it and let it air dry for a couple days before use. Breastshield/connector: This piece I wasn't sure I was going to use much. I was very concerned with cleaning it. Specifically, I worried I couldn't get my little nipple brush in all the parts. This is actually easier to clean though. With the Medela one at the bottom where the yellow piece connects there are all these little sections it's hard to get the brush in. This Maymom brand doesn't have all those little areas. I usually throw them in the dishwasher. Valves and membranes: The yellow valves have a slightly different pattern on them, but they function exactly the same. I can't even remember which of my valves are Medela versus this brand. It's nice having the extras this came with. The membranes are the same. Those little buggers get lost pretty easily, so it's nice having some extras of those as well. The only downside is they aren't compatible with some pumping bras. I was doing the home hack of using a sports bra with holes cut out. This product definitely didn't fit in there. I don't think it would fit with my old Medela pumping bra (which I hated and returned). Now I purchased Simple Wishes Hands-Free Breastpump Bra, Pink, XS-L and this all-in-one breastshield actually works with that bra. I don't like to use it though because I'm worried it will stretch out the holes. I like to pump quickly in the morning after my first feed to get all the extra milk out from the night before. This is a very brief pumping session and I use the all-in-one for this time since I don't take the time to put a pumping bra on. If you're looking for tubing and extra parts I absolutely recommend this product. The price is perfect and you get a lot of parts. I have recommended this to some friends and they are happy with the product as well. Update: I used thees for almost a year and never had any problems with them. I've even sold a few sets for Maymom by getting my friends to buy them. It's just such an amazing deal for everything you get. I had absolutely zero problems or complaints other than it not fitting in my nursing bra. I actually lost my milk on one side at about 7 months in and just pumped on one side, so it was easy just to hold it with one hand. I am still nursing my 16 month old, but trying to wean right now. I highly recommend this set if you're looking for lots of parts at a good price. ## Features - Contains 4 valves, 6 membranes, 2 tubes and 2 one-piece breastshields, 21 mm; Compatible with Medela Pump in Style pump parts.

S, M+, L, XL** A: We are the manufacturer of this product.First, measure the diameters of your nipples AFTER a pumping session. If you don't know how to measure it, follow maymom.com/nippleruler to make yourself a nipple ruler. Knowing these data, the general rules of thumb are that the inner diameter of the breast shield should be 1-2 millimeter larger than your nipple diameter. If you measure nipple diameter BEFORE a pumping session, we can only estimate that the breastshield shield should be 2-5 mm larger.Example: the diameter of your nipple after a pumping session is 23 mm, then choose the M (24mm) or M+ (25mm) breasthields. Furthermore, please also try the following check list to find the best one for you. Center the nipple in the tunnel of the breastshield. Now begin pumping and check the following points: Is your nipple moving freely in the tunnel? Is none or only very little tissue of the areola being pulled into the tunnel of the breastshield? Do you recognize gentle, rhythmic movements in the breast at each pump cycle? Do you feel the breast emptying all over? Is your nipple free of pain? With the above check list, a mother can easily assess whether she is using the right Breastshield size. All points should be "true", then you have the right size of breastshield.A correctly fitted breastshield prevents the milk ducts from being compressed, thus enabling an optimal emptying of the breast and maximum milk output when pumping. This helps mothers to maintain their milk production and supports lactation. It also prevents chaffing and tenderness of around the nipple area. **Q: Does this accessory kit fit the pump in style original, bought in 2005?** A: Yes, it will fit Pump in style, made in 2004. If not, it also includes a set of extra tubing connectors that you can use to adapt to your machine. **Q: Does it compatible with Medela Pump In Style Advanced Breastpump Starter Set-Model # 57081???** A: Not sure what all the model numbers coordinate to.. I have the medela pump in style tote from WIC, the tan one, and these we're compatible. **Q: I see that the product info says these pieces are steam sterilization safe, but is it also safe to boil them when sterilizing the parts?** A: Absolutely. I boil mine every other day. I bought 2 sets so I have 4 breastshields and extra valves. I boil all for minimum 4 minutes, sometimes 6 or 8. No problems so far. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Spectra vs Medela pump in style. *by W***M on April 5, 2017* Using these with my Spectra pump and the maymom Flange adapters, takes advantage of the superior pump of Spectra.

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! ## Frequently Bought Together - Maymom Breast Pump Kit Compatible with Medela Pump in Style Advanced Breastpumps NOT for Pump in Style with MaxFlow, 21 mm Breastshield - Medela Breast Milk Collection and Storage Bottles, BPA Free, 6 Pack, 5 Ounces, Compatible with Medela Breast Pumps - Maymom Breast Pump Bottle Compatible with Medela Pump in Style MaxFlow, Freestyle, Swing Maxi Pump, Maymom Breastshields; Compatible with Ameda MYA Joy, Finesse and Purely Yours Pumps; 8pc/pk --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/6150837-maymom-breast-pump-kit-compatible-with-medela-pump-in-style](https://www.desertcart.hr/products/6150837-maymom-breast-pump-kit-compatible-with-medela-pump-in-style) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-02*
