MaymomBaby Bottle Thread Changer; Allow Spectra S1 S2 Pumps Wide Mouth Flanges to be Compatible with Medela Bottles; Incl. Duckbills

Doesn’t leak and helps us save time pumping directly into the Dr. Brown bottles we use to feed

I needed this so that I could use different bottles with my pump. They arrived fast and are food quality.

With my first child I had a Medela pump and so had a stock pile of Medela bottles for breast milk refrigerator storage. I also had adapters for my Medela flanges that would attach directly to my Tommee Tippee bottles for direct bottle pumping as we used those to feed our first child.With our current family addition, I'm using a Spectra S2 and wanted to leverage all of the stockpiled bottles, etc. I used with my prior pumping efforts. These adapters supported that need! So far, three weeks into use, they still fit well with my Spectra flanges and Medela bottles as well as supports the use of the Tommee Tippee adapter to pump directly into those bottles. The latter has a two adapter in tandem experience and so makes it heavier thus I'd recommend some careful attention while pumping and some extra hand support if you're pumping hands free.So far no leaks but I'm extra careful when setting the bottles down (first detaching the tubing from the flange) when done pumping to minimize some accidental tumbles. I did have one knock over of a bottle with these adapters in place and a Medela bottle and thankfully no leaks though milk does then find its way into the thread area which results in some small loss of liquid gold when transferring no matter how much tapping you do (pumping mommas know the tap dance performed with certain pump parts following a pumping session!). I now have a variety of other standard opening feeding bottles and these adapters support easy attachment to those as well.Based upon my experience thus far, I would purchase again.Update 2/23/17: These adapters are still holding up well. I've had no leaks with them thus far. Also added some pictures to this review to show use of the adapter with a Spectra flange and a Medela collection bottle as well as the adapter doubled up with the Medela to Tommee Tippee adapter to attach directly to a Tommee Tippee bottle.

These work great connecting our Spectra pump parts to our Playtex Baby Pods (that is, the pump adapter). They also fit narrow Dr Brown bottles nicely. The gasket is a bit loose, however.

Good purchase. They work easy & well. SpectraS2 to regular Dr. Browns/narrow.

I ordered these to pump directly from my spectra flanges into medela and dr brown bottles. They worked great but I did notice 2 small watch outs. The primary watch out is that sometimes the seal will be "too tight" and prevent milk from flowing through the duck valve. Consequently I've had milk back up into the flange and into the back flow protector. The issue is easily solved by just loosening/turning the bottle slightly. The other issue is that when I hand wash I've had the rubber ring fall off. I anticipate that it'll eventually get lost as it continues to stretch out over time. I haven't tried using the adapter without the rubber ring but I think it'll still work fine as an adapter.

I use the Spectra breast pump that fits only wide necked bottles. I use the Medela storage bottles as I love the tray they came with and the tops that can change day and time. One problem. The Medela bottles are small necked so I can't pump directly into them. Consequence? I have double the bottles to wash at the end of the day. That adds up after a day of pumping and takes a lot of my valuable time and drying space away at the end of the day.Solution? These beautiful things! They screw into the flange and any small neck bottle can be screwed into it. I have experienced no leaks pumping into Medela bottles and Dr. Brown's bottles. I have used them with and without the purple O-Ring seal (one of them was lost to the drain while washing...oops!) I experienced no difference with or without the O-Ring so the original product that comes without it is just as good.It is easy to clean and has saved me a lot of time and bottle washing. This is truly a genius product in my opinion and I highly recommend it!

Fits great and allows my narrow Dr. Brown's bottles to fit on my Spectra 2 breast pump!

I bought this for my spectra s1 when I received it as I wanted to use my medela and dr brown plastic bottles with the pump as well. Fits snugly and securely and I’ve had no issues with leaking or anything like that. Takes two seconds to put on and take off. Definitely worth it for anything that makes pumping a little more convenient.

This fits my medela bottles and Spectra S2 pump easily with no issues.

I had a Medela pump with my first baby but decided to get the Spectra S1 for this baby. I have a whole bunch of Medela pump bottles I didn’t want to just throw away but the Spectra nozzles don’t fit on the bottles, these thread changers worked perfectly so I could re-use the Medela bottles with the spectra pump! Very happy!

I bought these to use on my bellababy double electric pump in order to pump into dr browns narrow bottles . It fits perfectly and works just as intended .
