Review: Find it very expensive - I already had Medela pump hence was left with only one option to buy the spares. But it is very expensive ## Features - NOTE: this is a Maymom product, not original Medela pump parts. This flange is ONE piece (meaning the shield and the bottle connector is formed ONE piece, not like Medela's PersonalFit's two piece design) - This kits contains everything you need for pumping except the main pump unit and bottle. You can use Medela bottles and many other standard sized (narrow) bottles on the market. - BPA free; DEHP free. Retail poly-bag packed; Sealed by the manufacturer - Satisfaction guaranteed by Maymom - - If you want to use a handsfree bra, Simple Wishes is the choice. It is not compatible with some home made hands free bra or Medela's hands free bra. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PRP47GV | | Best Sellers Rank | #43,579 in Baby Products ( See Top 100 in Baby Products ) #589 in Breast Pumps | | Brand | Maymom | | Customer Reviews | 4.6 out of 5 stars 2,872 Reviews | | Included Components | Valve | | Is the item dishwasher safe? | No | | Item Weight | 0.21 Kilograms | | Manufacturer | Maymom | | Manufacturer Part Number | asjkjkdsd-1 | | Material Type Free | BPA Free | | Model number | M001-2xxF | | Operation Mode | Manual | | Product Style | Standard | | Size | 24 mm | | Special Feature | Hands Free Usage, Portable | | Special Features | Hands Free Usage, Portable | ## Product Details - **Brand:** Maymom - **Operation Mode:** Manual - **Special Feature:** Portable, Hands Free Usage - **Included Components:** Valve - **Material Type Free:** BPA Free - **Is Dishwasher Safe:** No - **Style:** Standard - **Size:** 24 mm - **Manufacturer:** Maymom ## Images ![Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve - Image 1](https://m.media-amazon.com/images/I/61pouJzZJqL.jpg) ![Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve - Image 2](https://m.media-amazon.com/images/I/817XzfUUpeL.jpg) ![Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve - Image 3](https://m.media-amazon.com/images/I/61n10tFP0KL.jpg) ![Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve - Image 4](https://m.media-amazon.com/images/I/81ze7m0qAjL.jpg) ![Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve - Image 5](https://m.media-amazon.com/images/I/71TdYM0UQKL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐ Find it very expensive *by R***K on 8 November 2023* I already had Medela pump hence was left with only one option to buy the spares.
