I wish I had one of these about 40 years ago.

I highly recommend this product!"

"Miller Machine is the Best."

Hi - my name is Dave M., I'm a drummer in Toronto Canada and I recently bought a Miller Machine at Soul Drums here in town.

It's saving my life right now, I'm playing in the pit for a production of William Finn's "Falsettos" and it was a scary amount of choreography before I got the Miller Machine.

Great idea, easy to mount and play, totally awesome.
