    5.0 out of 5 stars Works with Spectra S2 as expected!
    Reviewed in the United States on 19 January 2017
    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.
