^^^ Wow a lot of recomendations here...
If you want a burning laser it has to be a focusable laser, since even with decent power if not focused it won't burn.
If you want to have fun a 405nm focusable laser burns very well... but for 50 Euros there is not much power you can get.
If you want check my latest review here

I'd say that laser is probably 150mW at best. Not 1.5W It will most likely degrade and become useless very quickly as well. For you I would recommend a <5mW 650nm and a BIC
burning laser, what do you used for?
I assume he would use it for burning? :yh:
