Vac-U-Lock - อุปกรณ์ปลั๊กถ้วยดูดดีลักซ์

The lever-release is the star here—locks onto my tile wall instantly with zero wobble, and swapping attachments takes seconds. I’ve had weaker cups slide mid-use, but this one hasn’t budged once since I mounted it.

Works exactly as promised on tile and glass, and the lever-release makes swapping attachments quick without any wrestling. Only gripe is the suction takes a couple tries if the surface has the slightest texture, but once it's on, it's on solid.
