I have owned this rugged, splash-proof speaker for about six months. I purchased it for week-long bicycle tours and camping. It is a combination of solar charger, battery and speakers in one unit. I charge my phone and i-pod when off the grid. The speaker has blue-tooth and auxiliary (wired) input and indicator lights for battery status, etc. I use the two loops to strap the speaker to my bike bag for listening on the road. It sounds great for its size. It even fits in a large pocket of cargo pants.
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.
