I have one and use on the inside wheel halves--it works great for that. But, I was a little let down using it on the outside spokes.

I love my mini Powerball. :thumbsup:
Much better than polishing by hand..
I also have the original larger version and I have not even used it as it is really to big for most of the detailing applicatons we would use on our cars.
IMHO don't bother with the big Powerball just buy the mini.
The mini also comes with an extension that allows you to reach some tight areas.

I liked it and it does very well, just don't expect it to clean really dirty rims.

i got the mothers one...but i wasnt impressed...im guessing its cuz i dont have foose wheels or something. it does however work good if you dunk it in soapy water and use it to "wash" the wheel
