Laser listening blocker and disruptor:
- This small device sticks to the window easily and prevents laser-type eavesdropping from a distance.

- The device creates sound at a frequency that masks all laser listening types. It’s small, compact and professional.
- This is a practical and professional small model intended for use anywhere.
- The device has a working time of about 50 hours.
