Tubing does the job but it is super flimsy and I'm expecting it to rip at any moment. I use it as back up when I wash my original tubing so it does its job. However I would be concerned if I has to use it day in and day out. (USE DISCLOSURE: I use my pump at work and in the middle of the night.)

These tubes are slightly smaller in exterior diameter and greater in overall length compared to the tubes that came with my Spectra S2. The length allows me to sit back in my chair and get a bit more comfortable. I have not noticed changes in functionality or output since using these replacement tubes.

Wish I would have bought these tubes 9 months ago! They are long but I like that! Great hold on the pump and the pump bottles! Highly recommend

I’ve had my Spectra S2 pump for about six months and have used it with then original tubing and parts day-in-and-day-out for that amount of time. Ordered "duck bills” as well as new tubing. Everything has worked great as a replacement thus far. Product was as promised.

So far these have worked great with the Spectra S2. I have not experienced any loss in suction.As with anything that is long, the tubing has the potential to tangle but the extra length is helpful for pump placement on a side table.The duckbill valves fit nice and snug and are much easier to remove than the original Spectra valves. I can also use these for the Medela Symphony. I am still skeptical about how well the space between the rings can be kept clean but I have not had any problems so…

Only had the product a day. It feels different than my original tubing, but that's actually a good thing. It feels better quality not as sticky. I have used it 3 times and it's very snug, almost to snug. Once I got the tubing on its hard to get it off especially connecting to the machine itself.

I like that these tubes are a little longer than the original Spectra tubes. It makes pumping at work easier, that I can leave the pump at the edge of my desk, and hook the tubes up each time I pump, instead of having to move the pump closer each time. There is more room on my desk for me to get things done while I pump.My only concern, is that after 4 months they've started to discolor/turn a little yellow at the end closest to the pump. Since it's a closed system, I'm not concerned with…

The tubing length is nice because it is longer. but after using this tubing for not nearly as long as the original spectra tubing. it already cracked where it is attached to the back flow protector. All I had to do was cut it with scissors to fix this. but This did not happen to my old tubing.

They fit right, and the extra couple inches makes a huge difference (te he he). Say goodbye to falling tubes that make you say bad words in the middle of the night!

I purchased this yesterday and ive been using it since I received it I see the difference from the original tubing this one is very long and and Great snug fit for my Spectra S2! I’m so happy!

The tubing seems slightly smaller than the original on my Spectra which makes it harder to take off but that can be a good thing when my toddler is yanking on it. I also really appreciate the extra length. It has made using the pump easier without having to get an extension cord of find a seat closer to an outlet.

I purchased this tubing for my used Spectra S2. It is slightly different than the tubing that came with the spectra, but seems clearer and not as thick. It fits snugly on the pump, which makes a very tight seal. Tubes are very long which is great! As they gradually stretch, they will be able to be trimmed for a better fit while still having plenty of length. Very happy with this purchase!Also shipped very quickly :)

I used these instead of the Spectra valves included with the pump because my Spectra valves kept falling off while I was in the middle of pumping. These fit very snug and I haven't had a single instance where they have fallen off in the 3 months I have been using them.

these are great - i feel like they are better than the spectra brand honestly, i haven't had any problems with them ripping like i did with the spectra brand. I use these everyday and would recommend.

I’ve used Nenesupply duckbill valves for my S1 almost since the beginning (since our cat chewed up the Spectra ones that came with the pump right after our son was born- cat owners beware!). I needed to replace them again, and decided it was probable time to replace the tubing as well, so I got the set this time. I really think new tubing makes a difference in the suction and I like these valves better than the Spectra kind! They seem to fit tighter to me, but I don’t mind it, and I swear they…

Another weird "almost as good as what came with my Spectra but not quite" accessory from NeneSupply.The tubes are narrower than the original tubes that came with my pump and while they fit, it's not without some jamming. I guess they can't copy Spectra exactly but I feel like all my NeneSupply accessories are only 80% as good as their original counterparts.

I love the extra length compared to what I received from my ameda Mya pump I didn't think the extra few inches really mattered till I had to stretch to grab something.

When my cat chewed through the tubing that came with my pump, I was desperate! These are kinda tough to put on, but they work and my cat seemed less interested in eating them compared to the original ones!

better than the original spectra tubing doesn't collect as much dirt or dust and seems to be less flimsy. Spectra original tubing doesn't hold up as well as this.

I’ve exclusively pumped for 4 years in total now and this is the best tubing out there! The longest length and they NEVER slip, I use these babies for months and months and months on end without ever having to change them out because of slippage.
