The updated version from a few years ago (with the extra two magnets on the axle) is an excellent pedal! I had sent mine back to the company for some reason, and when it came back, the magnets had been reset to the default positions. I was never able to find the right combination again, and stopped using it.
But I've been very happy with the Ludwig Atlas Pro (now the Speed Flyer) for the last 5 years.
Yeah, i am not sure if Mike is still around, i emailed him about getting parts to convert to a longboard and got no reply... Feel free to send over your old pedal.. time to go double bass
