Not for S1
This does not work with S1. The tubing is the incorrect size and the parts don’t work with original product.

Getting replacement parts straight from Spectra should have solved my problems but the duckbill valves are almost too big for the flange and fall off. Very frustrating especially paying $35 for only 1 set! Just go back to the knock off versions

Disappointed
I needed this as I forgot my pair when I went on a trip. I cannot believe there is only one bottle and flange for this price. Unbelievable. I needed it or else I would return it - this feels predatory. Very disappointed in spectra for this.

Plastic broke IMMEDIATELY.
I spent $70 for two of these and it immediately broke. Must be made cheaper than they used to! I was super engorged and needed to pump only to find the plastic was breaking into the tubing. No fixing that! What a waste!

Two boobs, one expensive mistake
Pumping was getting way less efficient, so I figured I'd get replacement parts and save on a full set. But this is just one boobs worth so I'd have had to buy two, which I learned the slow and expensive way. I lost supply and switched to formula.

WHY DOES IT ONLY COME WITH ONE SIDE. 35 dollars for only one side is absurd i would give zero stars if i could.

Hi there, thank you for sharing your feedback. The Premium Accessory Kit is designed as a single-side replacement set, which is noted in the product description and on the packaging, though we understand how that can be frustrating if you were expecting a complete double-pumping set. If you have any questions about replacement parts or need help finding the right quantity for your pump, our Customer Care team is happy to assist at 1-855-405-0993.

Defective for multiple kits
I wish I would have read the reviews. The duck bill valves do NOT fit. I wish I could attach a video. They slide right off in the middle of pumping and you have to contaminate the milk fishing it out. When I reached out to spectra they basically said "prove it" and that I can try my luck on a warranty IF approved.

Hi there, we're sorry to hear about your experience. The duckbill valves should remain securely attached during pumping, so what you've described isn't expected. We'd like the opportunity to troubleshoot the issue and, if needed, provide replacement parts. Please contact our Customer Care team at 1-855-405-0993 so we can assist you directly. We're here to help.

Not Flat Side Bottle
Annoying that the bottles aren't the flat side version for the S1.

While I love using my spectra pump and appreciate getting replacement parts through my insurance, I’m leaving a 2 star review because I used the new tubing provided by spectra to pump the other day and the milk wouldn’t come out. I was so confused because everything was hooked up properly and I was well hydrated and ready to pump but still nothing came out. I tried again in the evening and still nothing. I ended up switching back the original tubes and my milk came out.

Total Joke
Absolutely insane that this is a box of ONE. Spectra you should be ashamed. I forgot my pump parts at home for work and ran to target in a pinch. I thought $35 was expensive for two parts. Imagine my surprise when I opened the box and found one of everything. Side of the box says “for double pumping you’ll need two” who doesn’t double pump? I will not stop talking about this because it’s the most asinine thing I’ve ever witnessed. Imagine paying $70 for replacement parts with a new baby. BOO spectra. Very huge boo

Love the ease and convenience of getting everything I need for my pump replaced all in one spot and in my correct size. Using the right flange size has made a big difference in my pumping journey.

I love the bundle of replacement parts! It's so convenient having it all! I also really love having an extra bottle that comes with it. It is not only convenient for having an extra bottle for pumping, it is an extra bottle for baby to use!

Worth the money to buy the bundle and the Spectra brand parts. No "dupe" really compares the the output that this set up creates! Also the nipple is great option for when on the go. I can pump in the car with my S1 and use the same bottle with the nipple installed for baby when we get to where we are going!

Only ONE side...
only comes with one side which is NOT advertised in the title! I am pumping 8x a day and in emergency need of new pump parts. Target is not close to our house and only when we got back home did we realize it was one side. This seems wrong to charge $35 for just ONE side when it costs less than $5 in plastic. That's $70 just for one set and apparently they wear out in less than 3 months. Plastic is insanely cheap and corporations are just capitalizing on this. New parents won't be reading fine details and making money on women and hungry infants in the health industry in this country is appalling.

Why would you package this with only one of everything?! Needed replacements in a hurry and no where does it say there is only one of each product in the box! This is ridiculous.

Valves were only good for 6 weeks. The backflow protectors didn't stay on and fell all the time anywhere. I had to throw it out in to garbage and use Pump for mom brand instead. Overall not happy with Spectra breast pump at all. I don't understand how it proved to be number 1 breast pump.
1 reply from Spectra Product Expert team - 8 months ago
Hi Yulia, thank you for sharing your experience. We’re sorry to hear the replacement parts didn’t hold up as expected. Valve lifespan and fit can vary with frequency of use and cleaning methods, and the backflow protectors should stay securely in place when assembled correctly. We’d appreciate the opportunity to help troubleshoot or review replacement options with you — please reach out to our Customer Care team at 1-855-405-0993 so we can assist.

Absolutely worst nipple and cap design ever!!!! You have to align and twist it perfectly in order for it to fit on the bottle all while a baby is crying. I have twisted it 17 times and it still don’t align correctly in order to feed my baby. I’m throwing it away and using an easier bottle!! Spectra needs to make a better design.
1 reply from Spectra Product Expert team - 10 months ago
Thank you for sharing your experience — we know how stressful it can be when a bottle isn’t cooperating, especially with a hungry baby waiting. The nipple and cap should twist on securely without that much effort, so what you’re describing isn’t typical. One thing that often helps is pulling the nipple through the nipple-mounting ring before attaching it to the bottle — this usually makes alignment much easier. If it’s still giving you trouble, please reach out to our Customer Care team at 1-855-405-0993. We’d be glad to walk through it with you or arrange a replacement if needed. We're here to help.

Exact match for my S1, only thing is I didn’t realize (in my postpartum haze) is that it is only one set so I had to order another for dual pumping.

Wish I'd read the reviews before purchasing....
This only has one of each item. I had assumed it had two of each for the price, but I suppose it’s my fault for not reading the box. My recommendation would be to head to Amazon if you don’t need the parts immediately. You can get all the replacement parts you need for a heck of a lot cheaper, plus avoid what you don’t need (a 24 mm flange doesn’t fit me, but now I have yet another one).
