This little ring keeps the cleaning solution from dripping everywhere when I swap out the old one, and it snaps into place with a satisfying click. Makes the whole routine feel much tidier.

I was surprised how snugly this ring clicks into place — no wobble at all. It keeps the cleaning head organized and the whole setup feels much tidier now.

Snapping this ring on took about two seconds and now the refill stays put instead of wobbling around while I clean. It's a small, cheap part but it keeps the whole routine tidier, which is exactly what I wanted.
