Baby Bottle Thread Changer, Baby Bottle Converter Allow Spectra S1 S2 Pumps' Wide Mouth Flanges to Use Medela Bottles

Only used 2x so far and it’s been doing a good job. I’m satisfied with the milk collection and it seems to tread well with the pump and my medela bottles. So far no issues and am happy with the purchase.

I bought to use my medela bottles on spectra pump. Fits well. But it does make it a bit louder. It still quieter than the medela pump, but louder than when using spectra bottles and no adapters.

I purchased these because it is a pain to continually wash my spectra bottles in order to pump. Using these are great for any regular bottle and saves me time from washing multiple times a day!!

These connectors are great! I have a spectra S1 plus and was gifted a bunch of medela supplies by mistake. Luckily I found these bad boys and am still able to use my medela bottles with my pump! I have no experienced any leakage and I don't think they impact the power of my pump suction. So far so good!

The white adapter in the picture came with the Playtex silicone liners and allows Medela pump to pump into the liner directly, which means the top side (pump side) of the white adapter must be the same thread as the Medela bottle neck. But it does not fit as you see. Wanted to return but it's not a returnable item apparently.

These are great for being able to use medela bottles or small neck bottles with your spectra or other wide mouth bottle pumps. I had a ton of medela bottles and a spectra pump so I bought these and it was much cheaper than buying a bunch of new bottles and they take up far less room

I use these routinely to pump from my Spectra S2 directly into my Medela, Gerber, and Nuk ‘Standard’ width bottles. They do the job. I love being able to pump directly into the bottle we’re going to feed from so that there’s none wasted/leftover by transferring from the Spectra bottle into the feeding bottle.They don’t work though for using a ‘Wide’ nipple/ring with a ‘Standard’ bottle - they leak but I figured I’d give it a shot to see if I could use a wide breast like nipple with my standard 0.5 and 2.7oz Medela bottles. Nope. Oh well - we only use Standard nipples now anyway - my baby doesn’t care how the food gets in her belly as long as it gets there - NOW! :)They do what they advertise and I like being able to

I have a spectra pump & my girl takes the narrow Dr. Brown bottles. So nice pumping directly in to her bottles. Cuts down on extra parts that need cleaned and washed. Pumping time saver? Yes please!
