I was a bit sceptical about only 250mW laser but I was wrong.
This module laser works very well and with 5V (350mA) is able to cut brown paper and engrave in a good way wood, paper, etc...
It doesn't work o white paper....
Only bad point is the focusing, it is really an hard task to get focus, the spring works well but the roller isn't so stable and so to get focusing is not easy.
