Cheap and Waterproof 3000mW Blue Laser Pointer (IPX5)

After receiving the product, I couldn't wait to test its output power. The test result is more than 3000mW, which is really awesome!

The laser power is high enough, but the power consumption is large, and the batteries must be changed frequently. It would be great if these problems could be improved.

Complete accessories are included. In the 3W power range, this product is relatively cost-effective.
