I'm willing to buy a laser. It will be my first one.
What's the difference between 1W and 2W? They burn faster through stuff? Anything else special?
+ What do you quite do with your lasers? :)
I'm willing to be safe. That's why I want to know what is 'too powerful'. Such as when I light the laser on my hand and it burns immediately (= too powerful).
It will be my first laser so I want to take some cautions
