Nice metal look and works for years if direct copper wire contacts are present
Very nice product and build quality with metallic friction wheel. Contacts are iron (rusting results failure) so be sure to connect directly with copper wire to make it work for years

Light Cycle!
You'd be surprised what creative uses a thing like this can have! I've attached it to a stationary bike in a youth center and strung lights overhead. So fun!

Used for a light project on a snow blower
So far so good this worked out very well for putting a led light on my snow blower it didn't have a charging system on it so with a little welding to make brackets to mount generator so the wheel would ride against the main drive belt and it worked out very well so far
