This conversation is just droning on. If I had a nickel for everytime someone wanted an all powerful laser for $10... It's silly to just keep forking out $10 bills hoping to get lucky when you should just save them and get something with some quality.
Bottom line is it is a cheap unit and you are gambling on what you get regardless of whether it is a 301, 302, 303 or anything else that inexpensive.
It is much harder to burn with a 532nm because of all the fluctuations and mode hopping especially with units like that. If you want a laser that will light a matchance you are FAR more likely to get one if you buy a 405nm (violet/purple) or 650nm (red).
If you want a decent green you are either going to have to pay a lot more $ or increase your chances by buying some $6 3V or 5V 532nm modules from Fasttech which are usually pretty strong even without adjusting the pot. If you adjust the pot you need to do it properly or it is likely you will set it too high and blow it. This requires test instruments and not just fiddling around with a screwdriver. Don't watch those stupid pot mod videos. The last 3 I bought from them all adjusted to 120mW+. That kind of output isn't guaranteed but these $6 modules are the best deal going.
If you want ideas on very inexpensive good output units look at the links in my sig.
My links may show inexpensive builds but make no mistake, they are not "toys" and must be handled properly
