Okay, this must be a scam.
How do you rewind a DVD!?
Or how about.....
Gas Powered Flashlight
[Sarcasm]Why bother with a hand crank generator Flashlight, your solar rechargeable Flashlight,
or any battery operated Flashlight for that matter.
When all you need is about a pint of gasoline to get about 2 to 3 hours of light.
Ringing in your ears from the noise, and asphyxiated by breathing in all the toxic chemicals it is spewing forth.[/Sarcasm]
Oops, forgot the [Sarcasm] quotes.
