I need to rave about this product! I was producing only 3 oz of breastmilk prior to buying these parts. Now I produce about 25oz! What a big difference! I finally realized my original parts that came with my Spectra S2 were worn out after 3 months. I am glad I purchased these parts. They fit perfectly with my breast pump. I am happy that I can now provide food for my baby!

The parts were okay overall but the duckbill valve can't handle being sanitized (boiled) but only a week. Otherwise it's worth the money

I needed smaller flanges as well as replacement parts, so I thought why not get the kit and save some money compared to buying everything separately? I was immediately disappointed when this arrived. The flanges are VERY short and the backflow protectors are a milky cheap plastic that do not fit very well with the membrane (which is also harder than any other membrane I have purchased?) The duckbills and hoses were fine, so not all is lost. But overall, I wouldn't recommend this kit unless on a

Overall this is a great deal, not sure if I got a bad set or what but the backflow protectors fall off the flange constantly. It’s as if the piece that you stick into the flange is too small so it just easily falls out. It’s a pain in the *** & I get annoyed each time one falls off and falls onto the floor as I’m walking to the kitchen with my milk. It’s happened while I’m pumping as well which is annoying too. I just wish they fit in better, if it wasn’t for that they’d be perfect.

There’s a reason these are half the price of the authentic parts. They look good but don’t work.I bought these to replace my parts for my Spectra as one is supposed to do occasionally. I was excited because everything looked the same, and they were new! But the back flow didn’t seem right. The flange also didn’t fit with my pumping bras the same so I kind of had to support the bottles a bit, which defeats the purpose of the pumping bra. I dropped from 5oz a session to 2oz. I was thinking…

The box I received was clearly opened. The tape seal was torn, the box was partially ripped, and the plastic had been opened and resealed. Since these are supposed to remain sterile parts and not be returned, I was surprised to see such an obviously used product be mailed out by Revain. As a nursing mom, I know another mom probably tried on the flange, realized it was too big and returned the item. Since I was planning on sterilizing the parts anyway, and frankly, my nipples were sore from too…

I bought these for my Spectra S2. I like how the flange tunnel is longer than the original flanges. All pieces work great.

Ftm. Everything is fine so far. No real complaints, except the flange is opaque and I’m one of those who likes to look at the output and if the nipple is positioned correctly. So I have to use my flashlight to try to see through it. Other than that it’s ok. Does what it’s supposed to.

I have a spectra pump and the actually brand name for a pack was 45 dollars for replacement parts. That is a bit much for parts you have to replace like every 8 weeks. I love these alternative brand. They are almost exactly like the name brand ones. The only difference is the white bill but it still works really well.

These parts work ok with Spectra but I found the suction not as good and the pipes are looser on the backflow tips. I have to keep tightening them on every time.The flanges are ok but not as wide neck as Spectra ones in case you have larger breasts.Overall they are not bad, just not as durable as Spectra parts.
