Hi, The seller told me that this is a low power laser and no need to wear safety glasses. I found that it is approximately 13mW. Is it considered a low power ?. Do I need to wear a safety glasses at these power or just common sense ?

Here is seller message

The laser you have bought is safe,and it is great for creating various visual atmosphere, sky pointing, illumination, or other professional usages.Don''t worry about it.

Yes, no need to wear safety goggles with it, just be careful & don't aim it near your eyes :)

Is it safe to use in a presentation ?, I know that blink reflex will not help if I took a direct hit, what are the possible injury that could happen? Will it be permenantly or temporarily ? Best

You could use it in a presentation if you want, but it won't be easily seen. A direct hit to the eye could cause injury so it would be better if you kept it with you at all times. At 12mW's temporary damage to the eye could occur, but it really depends on duration etc...
