  1. The G20 light is the best pocket flashlight I have ever used. I am an automotive technician, and I use the light all day long. The one I currently use, I have been using for at least a year. Last week, I lost it. This afternoon I found it. It had been left in a work shirt and had gone through the wash and I found it when I took the cloths out of the washing machine. The flashlight still works. Now I have a great clean light to go to work with tomorrow morning.
