ซีลกระบอกสูบ Comfort

Sliding it on was easy enough, and the stretchy material does what it says, but I found the seal shifts a bit during longer sessions, requiring a quick readjustment. It's a decent upgrade from bare pumping, just not the game-changer I hoped for.

The stretchy seal does make the session a bit more bearable, so that part’s fine. But it’s tricky to slip on without it bunching up, and I’m not sure it’ll hold up after a few more uses. Works okay for now, just not the upgrade I hoped for.
