Review: Spectra vs Medela pump in style. - 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 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: Great product and customer service - 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!!!

## Questions & Answers

**Q: How do I know what size to buy? 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.

### ⭐⭐⭐⭐⭐ Amazing product, Amazing company!
*by K***. on May 2, 2016*

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!
