Powerful and Cheap 500mW Red Laser Pointer with Mounting Bracket

I bought the 500mW version, and the actual measured power was 600mW, which exceeded my expectations.

I chose the 500mW one. The red laser is surprisingly stable. It ran for several minutes and barely got warm. I measured the actual output at 460mW.

I purchased this red laser pointer a few weeks ago and was so impressed with its build quality and high power.
