High-Power and IPX7 Waterproof 100mW Red Laser Pointer

This thing is not as powerful as claimed. I tried to light a match with it but failed. Maybe I need to adjust the focus properly first? I don't really understand, but it's not what I need.

I waited two weeks for the delivery. The laser is overspec (more than 100mW) and can ignite matches. It is waterproof with rubber sealing. Highly recommended.
