I've had my Octane for about 2 months now and use it almost everyday.  I was reluctant to spend the money, but now I'm so glad that I did!  What initially impressed me was the small footprint- I live in a 550 sq. ft. studio apartment, so that was very important to me.

I also live above someone and the Octane is very quiet- just a swooshing noise that is barely audible.

Would definitely buy again... very happy!
