My husband is the buyer of the Octane, I just went along for the ride. WOW what a machine! I use the Octane like a walk in the mud. I call it " trudging through the mud" and what a work out. Everything in the above reviews are spot on. Pricey but so worth it. It's not very pretty ( reminds me of a bumper car) and its not a clothes line so use it !!!
