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.

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!

LOVE these
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.

Worked better than expected
Was able to use this to hack the Medela kit that we got from the hospital to be able to use it with our baby Buddha pump.

Converted Buddha pump to work with medala parts
I used a medala pump during my first pumping journey and this time went baby Buddha. I still had all of my medala flanges so was looking for a part to convert and this works well. I still have just as great pumping output as I did with the Buddha flange and bottles

These are nice and cut out another connector
These are nice and cut out another connector! The only thing that sucks is the top piece that goes to the spectra tubing separates from the rest of the backflow. They work best with the top piece of the spectra backflow. Which is fine because you don’t have to wash the top piece anyways because it doesn’t get milky. I love using my freemie cups with my S1 but you have to have extra backflow. They also come with a brush that fits all the tiny tube connector pieces which is way better than the pipe cleaner I was using.

Convenient
It's great to be able to use Medela parts with a Spectra pump. (The description says you can't use these with the Spectra parts, but you totally can; it just sticks out farther - actually I think it fits more securely than the backflow protector that came with the Spectra parts.) I do sometimes have an issue with the transmission of suction: I'll start pumping and nothing happens, as though something weren't connected well. It appears that the issue is with the Medela valve and membrane assembly - if I take the bottle off and squeeze the valve/membrane shut with my fingers, the suction is fine, so I don't think there is actually a problem with the backflow protector. The same set of parts will work fine with my Medela pump. My guess is that with older membranes they don't lie perfectly flat, and something about the Spectra's suction pattern in Massage mode is different enough that it doesn't squeeze the valve shut. Again this isn't a problem with this product as far as I can tell, just a note on using it.

Works well
I’ve been using these for a few weeks now, and they seem to work well. I’ve experimented with the Spectra backflow protectors with the Maymom adaptors, these, and the collection kit that came with the Spectra pump - suction seems to be the same across the boards! Other reviewers have mentioned there is condensation or moisture in the backflow protector after using these, which is true. However the same amount is produced when I use the Spectra kit, so it seems pretty normal. The other thing I notice popping up in reviews is the durability of the silicone diaphragms/inserts, so I’m curious to see how these hold up. The Spectra ones need to be replaced every 1-3 months, so we’ll see how long these ones last.

J’adore ce produit! Il marche super bien avec ma pompe et en plus ne perlait pas que le lait sorte en cas qu’il tombe. Super contente!

Works exactly as I wanted it to, fit to my medela and maymon flanges so I can connect my bella baby pump. Saved me a fortune in having to buy new flanges

These worked great, as expected! I used them to make the Bellababy wireless pump compatible with my medela flanges and bottles!

Aucun commentaire à faire, c'est tout simplement parfait.

Got these so I could use my medela pump parts with my spectra pump. Such a clever wee product- you just attach to tubing and then use medela flanges, pump parts etc. Works v well!
