As long as you use it correctly.
Never point it at person, animal, plane, boat etc.
Only use it as an astro pointer.
Get the correct user license for where you live.
There is no danger & you shouldn't have any problem.
If you intend to use it for anything other than astro pointing then I suggest you shouldn't own a laser pointer.
Also, a 30mw is pretty bright. If you intend on attending astro gatherings where people are imaging, I suggest you don't use it. The beam will destroy an image if passed through the image field.
