has anyone used one of these yet? what do you think of it?

 

I haven't used one, but I took a look at one in person, along w/ the hub you have to buy (Jegs is local to me). They both looked like quality pieces, and nothing about their apperance would make me hesistant to purchase one.

 

For about $100 more you can get an ATI balancer... much better IMHO.
