Pump Converters

They don't work 100% and are prone to fall off if you don't screw it the right way, which yes is obvious, but even when you think it's on right, if you slightly over tighten it it will pop right off.

I use this converter to connect spectra flange to the ceres inner, and I see it can also attach to the top to serve a a feeding bottle but I haven't used that yet. No leaks, easy assembly, wish this would have been offered as a package when I made my purchase though, could just make a drop down menu for add-ons specific to each pump

Work and personal travel just got less stressful thanks to my Ceres Chill! It’s so easy to carry on milk I’ve pumped and keep it cold. I also used it as an easy milk warmer on my trips! Highly recommend.

This has changed the pumping journey, it is so great to have all my pieces in one place vs shuffling around bottles and being worried about keeping the milk cool. Worth every penny! The pump converters work seamlessly with my spectra.

So long as you remember to differentiate the regular ones from the Lasinoh, these are great! The little purple "o" ring does tend to stretch out quickly and fall off, so I've had issues with some leakage and losing the o ring for one of the two, which is frustrating as it's a more challenging shape to find since it goes over the lip. But if you're more cautious than me, these do exactly as they should and allow you to combine the narrow neck to wide neck bottles or pump parts. I would definitely recommend this product!
