For the most part these were worth while if you know the flanges work for you.I did find the tunnel on the flange to be just a little shorter than the flanges that came with my spectra S2.

The little white things that cause suction lost suction so now I'm having to buy spare parts. Wish it was better quality. The bottles are great they work well with the spectra. But it's already expensive enough just to purchase extra parts now I have to order parts for those parts.

Great product. works well with my Spectra pump. everything seems to work just as well as the OEM parts. The duckbills are the only part that does not look the exact same as the oem parts, however, they function the same.

I notice no difference between the spectra brand and these well minus the price! Works great and there are more flange size. MAKE sure to go to site so you get the right size will make a HUGE difference for your pumping journey!

These parts fit the pump just fine, however the backflow protectors aren't very secure and have popped off while using the pump a number of times already, thus the reduction in stars. I wish I had just gone with the Maymom or Spectra original. I'm really disappointed in the backflow parts and may have to buy replacements of just those as I feel like I'm losing suction and hate when I have to reassemble them mid-session.

These work great and the duckbills are easier to take off than the original. The only down side is that they cannot be used with the Medela bottle adapters that I bought for my original spectra flanges.

Good set to go with my Spectra S2. I was well overdue for parts and these are a great set. I could tell a positive difference in my pumping. Not a big fan of the bottle shape, but nothing that would deter me from buying. I actually bought a 2nd set already for work. I do like the long tubing. I would definitely recommend.

Perfect for the Spectra s1. I wish it came with multiple flanges and bottles as the other pieces are easier to use again and again.

I purchased this set in hopes of replacing my original set. Overall they work perfectly and I really enjoy them. The only issue I have is that the bottles fit very snugly into the flanges at first. But after the first few washes they now fit loosely so I have to make sure they stay tightened when I'm pumping, otherwise they'll drop out and everything spills.

I’m so glad that I ordered these. I was on edge since they’re not original Spectra parts but in my opinion they’re way better than the original parts! Highly recommend!

The parts themselves are fine, but I use a spectra size 28 flange, and bought the 27 thinking this would be okay, but it really is too small.

I usually love everything I get from here. I got a new size flange and the back flow protector has broken. It fell 2.5 ft off my desk while trying to get set up and it broke! the other one fell too but is fine. Im hoping this is just a fluke, but now I am pumping one breast at a time today and it is very time consuming. Everything else has been great though.

I like these spectra parts better then the originals! The bottle is easier to read and the duck flange is much easier to remove.

The product did not work for me, but it was quality and compatible the company was great working with me for a refund! Thanks for attention.

Great alternative to spectra S2 parts. Only complaint is that I wish the bottles would hold one more ounce! They are a tad small.

I have been very happy with these pump parts! It was a great deal to have both sides come together instead of having to buy both separately from spectra. They are completely compatible with my pump and easy to clean. The instructions they send along are very thorough and informative, easy to understand as well!

I really like the price of this set so I decided to give these a try. I was skeptical to purchase these because it is $30, but comparing having to spend $60 with the actual Spectra manufacturer it is worth trying them out. I'm currently using them for the first time and they seem to work great. The suction power is exactly the same as before. And as far as people being concerned about the little piece on the back flow thingie breaking, if you don't handle them rough it should be fine. And even…

These are great for the Spectra II. All the parts are compatible and work well. The only part that doesn't fit is the actual bottles that hold the milk do not fit into the bottle holder on the back of the pump. They are not the same shape as the original. Otherwise, I highly recommend.

The funnel area felt a bit sharp but works well with my spectra. I just used a nail file to make the edge dull. Almost felt like it cut my breast.

This also fits my Spectra Gold portable (though note it does not come with the white adaptor that connects tubing to the machine). I like how it comes with caps to close the bottles to store milk after pumping.
