Video review: Burn machine speed bag 12 lb.
Thank you to the OP awein for posting this deal.
I'd never heard of this product or Muscle HQ before and would never have found this great product were it not for SD and the OP of that thread. There were a couple of threadcrappers in there saying that this wasn't a good product ~ I disagree, it's not really comparable to a speed-bag alone as you can go up, down underhand, overhand and sideways with this thing as well to work different areas.
bang for the buck rating: 9/10
