Good for basic alignment – 2~5mW 650nm Cross Laser Module (3V) Reviews

Pros:
Tiny, compared to other line/cross lasers. Lines are sharp and solid center to edge.
Cons:
I bought 2 of these and both had slightly misaligned prisms, meaning the lines weren't 100% perpendicular and their length was different.
Other:
If you're looking for a precision instrument that projects 100% perpendicular lines, get 2 line lasers instead. You'll be able to alight and calibrate them, unlike this version that has all of the optical components inside a sealed enclosure.
Bottomline:
Get this laser if you're looking for an entertainment-grade device (eg. a laser for a smoke machine light show or a toy weapon targeting system). For precision measurement and alignment either get a professional cross-laser from a home hardware manufacturer, or a pair of line lasers that you'll be able to line up and calibrate manually.
