## Description

desertcart.com : Maymom Backflow Protector, Long Stem, Compatible with Spectra S1, S2 and 9 Pumps, Compatible with Medela Flanges and Medela Parts; 2pc : Baby

Review: No more hack needed!!! - I have used a Medela PIS for the past 3 children and though I have wanted a Spectra, I finally got around to getting one on my 4th pregnancy. In my area I can't find Spectra parts unless I order online and I already had a lot of Medela parts and a system for pumping I liked. I had seen multiple videos and tutorials on how to hack the Spectra to fit Medela parts and then found this. It fits perfectly. I use the personal fit system with 27mm flanges and have no trouble. I don't lose suction, the fit is snug but not tight, and I'm so satisfied it all works without needing to hack anything. The box comes with 2 adapters ready to be plugged into your Medela flange set up and hooked up to your Spectra tubing. Nothing else is required to get everything to work. The back flow preventir comes apart for cleaning easily. Would definitely recommend this rather than trying to hack the Spectra.
Review: They do what they are supposed to - These are really great and work perfectly with Medela personal fit parts! I have these backflow protectors as well as the Spectra ones with the little yellow adapters for the Medela. I did now know these existed when I bought the adapters. I would say if you are planning on using Medela flanges only, I would prefer using these over the original backflow protectors with the adapters, mostly because it's a simpler set up and easier to clean. That being said, when I started to exclusively pump, I did use both Spectra and Medela flanges, so the other set up came in handy as well. The little brush that comes with the Spectra pump is great for cleaning the long and narrow part of these protectors. As far as function they work as well as the originals. The Spectra tubing stays on very nicely and I havent had any problems with them disconnecting when they are not supposed to. Highly recommend these!

## Questions & Answers

**Q: What is the use of these backflow protector?**
A: if you have a spectra pump and want to use medela like breashields, this protector can do it.  this protector connects between medela like shield and the tubing from your spectra pump.

**Q: Can you use these parts with the spectra s2? The product description says yes, but the picture says no.**
A: If you have a medela flange and want to use it with S2 pump, buy this backflow protector.  If you have an original spectra flange, this backflow protector will not fit it, but it can still fit the tubing end that come from the pump main unit.

**Q: Can i use medela tubing with this or would i need to purchase spectra's tubing?**
A: HI, you can use medela pump in style tubing with this one as long as you cut off the tubing adapter on the tubing.  it is tight fit, but it will work.

**Q: Does this work with spectra M1?**
A: The short end can attach to the tubing from M1, but the long end will need to connect to a Maymom or Medela flange, not a spectra widemouth flange.

### ⭐⭐⭐⭐⭐ LOVE these
*by R***E on June 10, 2017*

I wish I had found out about these sooner! After returning to work with my first baby, I had purchased several extra shields/valves/membranes for use with my PISA so that I wouldn't have to wash one set again and again (because pumping at work is hard enough as it is). I bought a Spectra for returning to work after my second baby but didn't want to spend all the money on extra parts. It's been rough. Thanks to these Maymom gadgets, which work very well, I can use all my extra parts! So happy. GREAT product. Ingenious. Saves you the trouble of having to hack your own solution.
