The Cubii is a good exercise machine that can give you a decent leg workout.
This unit does all the work for you, and is good for someone who is VERY sedentary, has mobility issues, and needs to improve their circulation.
That being said, I am thinking about getting it, because I do have those health issues and during my busy season at work I am sometimes sitting at my desk 12-16 hours a day. So maybe this would help me. I think I will do some more research today.
I wonder if this is their latest and greatest model, or some older model they are trying to get rid of at QVC? I wish it had more speed settings besides 1 and 2.
