Focusable 500mW Green Laser Pointer with Batteries

I don't do many product reviews, but this laser is bang for the buck and works great. Instructions are limited, but it's straightforward if you know what you are doing a little bit.

The green laser is bright both during the day and at night. Also, the battery life is amazing. You won't regret this purchase.

The green light is nice, and the light patterns are attractive. I've noticed the battery life is much longer than I expected, which is great.
