This ultra-strong suction cup, with manual lock, allows you to attach your vibrating speaker to a window, a mirror, or any surface that would be as smooth as glass.
The lock is done by sliding a button: it is then impossible to remove the suction cup without unlocking it! Ideal to vibrate your windows and produce a clear and powerful sound throughout the room!
Designed for standard windows, do not use on ultra-thin or fragile glass.
