- No instruction to adjust focus or crosshair quality, usage, etc
This is cheap laser pointer that use diffraction grating in front to generate crosshair type. Output is ok, although it is not strong enough if you want to shine it more than 5 meter range in normal daylight condition. Also the line is getting too big once you exceed past 5 meter. It is good for short range line generating usage. You can also take the front optics out and stick it to other higher power laser pointer to make it crosshair type.
