Cheap 520nm 50mW Dot / Line / Crosshair Green Laser Module

This laser is perfect for a beginner or maybe a backup for those who are more experienced. This little thing works for me just fine.

For the build quality, it's cheap!
I wouldn't recommend using it for precise commercial metrology projects, but it's perfectly good for hobbyists. The laser light is very bright and has a long range.

This green laser module arrived in a week and works great! I will be buying a second one soon.
