Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

I received a 445 nm laser pointer from Aliexpress. the seller claimed that it is only 10 mW. It is brighter than my 5mW green laser. It has no warning sticker. I found that it can burn through black cards, and CD cases. I'm afraid because I did not wear goggles while testing it. I did not get any direct hit. I'm afraid from reflection of white surfaces like wall also, my monitor screen is black; will it reflect the full power ?. My vision does not changed; is there any chances of a damage from white surfaces like a wall from short distances 3 or 4 meters ?. I'm really afraid.
