I use these new Nickel Metal-Hydride batteries now in my radios, flashlights etc. I hate throwing away little environmental hazards in the form of Alkalines and I hate always having to buy batteries. These new cells have almost the same operational life as an ordinary Energizer but you can use them over and over and over.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
