Great product fits spectra s2

My child is almost a year old and I've been at work in the office again for about 5 months (I had 4 months at home with her, exclusively breastfeeding). When going back to work, I knew that I needed something that would keep my supply up to the highest capability possible. After using my spectra s1 parts 3x+ per day for around 4 months, a friend mentioned that I might consider getting replacements parts, as the valves aren't meant to last that long. After several successful purchases from Maymom, I was confident these would do the trick. I would argue that since you can get the smaller flange size, these are BETTER than the spectra s1 parts that come with the pump. If you are on the fence, do it.Happy pumping!

These fit perfect with my Spectra2. I love that they come with additional seals to prevent leaking. The two complaints I have are that I wish the set came with the second generation duckbill that have the pull tab fit easy removal. Also, i wish the blue seal that is meant for the flange when connecting the bottle, would stay on better. They are constantly falling off into the bottle of milk or on the floor!

I love theee for the fact that they fit my nipple size. It hurts like heck with the sizes Spectra sends with the pump. The downside is that the caps leak no matter what even with the annoying gasket. They leaked precious milk twice then they were in the trash. TERRIBLE TOPS!!!! I use the caps I got from specta and they never once leaked with these bottles.
