At the end or beginning? It’s not sucking properly **Q: Will this work with the spectra hands free cups?** A: They did not work with my spectra Cara cups. Had to buy the long inserts instead. **Q: Will this fit in momcozy hands free breast pump?** A: It does, but it’s not as tight of a fit as some other brands. **Q: How can I keep these inserts from backing out of my medela 24mm flanges?** A: You should be able to push it in enough where it won’t pop out, if that keeps persisting I’d return and get new ones. Mine fit in perfectly. ## Customer Reviews ### ⭐⭐⭐⭐ Seems good quality *by on Reviewed in Australia 13 April 2023* Soft. Seems good quality. I can’t comment if comfortable to wear as the size wasn’t right for me, so I didn’t use it and unfortunately waste my money. ### ⭐⭐ Runs small *by on Reviewed in the United States 14 June 2026* Runs small I size compared with other brands. It damage my nipples due to sizing. ### ⭐⭐⭐⭐⭐ A cheap alternative that works! *by on Reviewed in the United States 29 June 2023* I’ve been struggling with milk production using a Zomee double pump as well as an Elvie Stride. I realized I needed a smaller size cup but didn’t want to shell out the money for replacement parts for both pumps. I purchased these and they have worked beautifully! Pumping is no longer painful and my milk production has increased. ## Frequently Bought Together - Maymom 21mm Flange Insert Compatible with 24mm Elvie Single/Double Electric, Elvie Stride Wearable Cup, Compatible with Medela PersonalFit Flex Shield, Not Original Elvie Replacement Pump Parts - Maymom 21mm Flange and Duckbill Valve Compatible with Spectra S1 Spectra S2 Spectra 9 Plus Not Original Spectra 20mm Replace Pump Parts Spectra Flange Spectra Duckbill Valve --- ## 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.us/products/486109873-maymom-funnel-inserts-21mm-compatible-with-medela-and-24mm-spectra](https://www.desertcart.us/products/486109873-maymom-funnel-inserts-21mm-compatible-with-medela-and-24mm-spectra) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-18*
