Thank you for looking.

This item has been opened once for a functional check.
It is designed to be attached to windows.
When turned on, it will emit a beep sound, indicating it is operational.
If the window vibrates, a loud 125dB alarm will sound with a beep beep beep noise.

The sensitivity can be adjusted with a dial to prevent false alarms from minor vibrations.

An instruction manual is included, but it is in English. I have provided a brief explanation here for your convenience.

The product includes trial button batteries, but they may not last long. Please replace them with new button batteries as needed.

For your reference, I have used it by applying double-sided tape to the window, then attaching the non-adhesive side of masking tape to the double-sided tape, and finally sticking the adhesive side of the masking tape to the window to avoid leaving tape residue on the window.
