I have a set and love them. Mine are the single color, no remote version. I put batteries in in April, and they are still working great as of last night. And this is my daily driver.
I was at Heart of Washington last weekend, and after coming in from a ride at dusk, a couple people came up to me asking about them. They ar ea great conversation starter.
They fit right in the hubs of an RT, easy to install. However, one thing Ii didn't think about but Sue from squared Away says they are a bugger to get out, as the dis-similar metals really bond, and they need them out to do the alignment. So, they charge more if you want an alignment and have them on your bike. Other than that, i think they are a cool farkle, that does get attention.
