Good value
Solid module for the price. Brightness is decent but not adjustable without PWM. Shipping was fast.

Great for Arduino projects
Works perfectly with my Uno board. The laser is bright enough for indoor alignment tasks. Easy to wire up.

Pin layout confusing
The module works but the pinout wasn't clearly marked on the board itself. Had to look up a diagram online.
