    Great complete set for pumping moms
    This kit comes with everything needed for daily pumping — flanges, bottles, tubing, and replacement parts. Everything arrived on time, packaged securely, and the materials feel durable. The bottles are easy to wash and clearly marked, which makes storage simple and accurate. They’re labeled for 6 oz but can actually hold about 7 oz if filled to the top, which is a nice extra capacity.I’ve been using the set consistently and found the suction to be reliable with no leaks from the valves or tubing. The parts are fully compatible with my pump, and having backups has made my routine much smoother. For the price, it’s very convenient compared to buying each item separately.Overall, this is a well-made and practical set for any pumping mom. It offers great value, dependable performance, and saves time when you need spare parts ready to go.

    Fits my Medela Sonata Smart Double Electric Breast Pump
    If you’re looking for small breast pump attachments, this is for you! I’ve been searching everywhere for the Medela attachments for smaller sizes than the standard 21mm and FINALLY I found some! Super durable and fits perfect to my Medela Sonata Smart Double Electric Breast Pump!

    Better than original spectra parts!
    Okay.. I’ve had some time to use this to see how it would compare to the original spectra parts. I like this even more!! The shields feel more comfortable on this one. It doesn’t feel as harsh when the suction goes up. Then the flange!!! I love that they included the ones that have the tab. My original spectra ones don’t have that and I always struggle to get them off when it comes time to wash. Output is the same with both brands. Overall great purchase.

    It started off great but….
    I was super excited to use these new parts since my original ones have put in so much work already (almost 6months) and a new set was long overdue (really overdue…). I got these to use with my s1 spectra and its a good fit. When I first started using the new parts, I was pumping almost double the amount of milk (about 5oz or so every 30min) and was thrilled. I got my supply back up and it was great. Not even a month later, the ducts are now so loose that it will literally fall off when I open the lid. Now I am barely pumping 2 ounces (if im lucky) after 30 min. I am so disappointed and worried about my supply decreasing significantly since my wearable pumps isn’t pumping much milk anymore over the last few days. I decided to order new parts specifically from the spectra brand and am just waiting for it to come in. In the mean time, I hope my supply won’t be in trouble by the time these new parts come in. So anyways.. it start off great but now its probably done more harm than good. Would not recommend unless you need it for temporary use.. especially with the ducts falling off as easily as it does..

    I’ve been using my Spectra pump and have always had issues with the original duckbill valves. Every time I took them off to wash, I was so worried about tearing or damaging them, and it happened more often than not.That’s why I was thrilled when I received this full set of replacement parts. The seller has made a small but absolutely genius creative update to the duckbill valves: they added a little pull-tab!This tiny tab is a total game-changer. It makes installing and removing the valve for cleaning so easy and secure. I no longer have to nervously pinch and pull at the delicate silicone, which means no more accidental tears or wasted parts. It’s such a simple idea, but it makes a world of difference in everyday use.The quality of the entire set is excellent and works perfectly with my pump. If you’ve ever struggled with damaging your valves, this design is an absolute must-have. Highly recommend!

    The Spectra is a bit harder to get in Canada, so finding parts for it has always been a concern. This set is quite versatile in combination with the original accessories our S1 Plus came with, and personally I wasn’t a fan of the original bottles so I prefer the ones from this set instead. Otherwise they work great and I’m just so glad they carry so many flange sizes to make the Spectra accessible to more Canadians.

    Overall the pieces in this set are compatible with the Spectra S1 including combining it with original parts, but I found the plastic feels a bit thinner and cheaper at least for sure with the membrane caps. The valves felt maybe a bit thinner too compared to the original ones but time will tell if they last a similar length of time with similar use. Stand up fine in the bottle washer as well.

    So glad I got this kit for my 2nd round of pumping with kiddo #2. The tubing is about 6″ longer than the tubes that Spectra supplies, so that extra slack is very helpful with my pumping/feeding chair and trolley set up. 1 star off as the provided bottles have measurements built into the plastic and it can be difficult to read during late night feedings.
