The adapter works great with out bottles and expressing machine. Would have given it 5 stars but the thread on the avent side is just a little out. This doesn't affect the seal it just makes them a little harder to connect and disconnect.

Fantastic product. What is not to love with something that saves time and money.

Glad I bought these as it meant I didn't need to go and buy new bottles to connect to the flanges I also bought from here. Interestingly I could connect the spectra bottles but also my pigeon ones, which didn't connect to the spectra flanges. This meant no more awkward decanting on my morning pumps where I sometimes need to change bottles mid pump.

Whilst this product is advertised as being suitable for the avent natural glass bottles, that is not really the case. You can get the adaptors to bite onto the thread far enough that if you were just using these to connect glass bottles to breast pump flanges, which is what I'm using these for, they are adequate, but they the downy screw down to anywhere near the much vaunted sealing ring in the description. Not even close. If you actually want the seal to be leakproof, like attaching a bottle nipple, these are totally not suitable for the glass bottles. Pay the extra money and get the avent ones.
