This is a good and cheap laser module, the power is really god (It's not even comparable to those cheap laser diodes that you can buy for a buck in your town) Focused line can be useful for a lot of project, it's up to your fantasy. It accepts a wide range of voltages, and the optical output doesn't dims much with the voltage.
Really i can't think of any cons...
The module can be disassembled really easily, so you can use it or the laser in the way you want!
