I call this my dream machine. I went from a size 16 to a size 7/8 using the Octane elliptical on manual mode, without even using the bells and whistles! I tried out almost every elliptical on the market before purchasing the Octane. I like the stride of this machine and prefer it over the Precor ramp model. It also allows you to squat and work your glutes if you are so inclined. When I bought the Octane I had severe knee pain from trying to jog, and I had no problems at all with my knees after using this machine. The Octane is worth every dime and more.
