The threads are solid and it screwed on without any wiggling, which was my main worry with an adapter. Pumping straight into the bottle with my non-Medela setup has been a total game-changer for my workday.

Finally, I can use my Ceres Chill with my pump without fiddling with a bunch of extra parts. The universal adapter threads on smoothly and holds tight, so no leaks when I'm rushing between sessions. This little thing solved my biggest pumping headache.

Took it straight out of the box and screwed it onto my pump, and the universal wide mouth fit was seamless. It clicks into place firmly with no wobble or leaks, which is exactly what I needed. This little adapter just saved me from buying a whole new pump system.
