I am very satisfied with the premium model that I purchased. At first I could only stay on it for about 1/2 minute at a time and then rest in between. Now I am using it just about every other day and can stay at it for about 20 minutes. It is just the thing to allow me to exercise in the comfort of my own home and not have to get my aerobics by going outdoors in the New England winters we have here, which is catastrophic to my lungs. . My blood pressure is measurably dropping within the 'safe limits'.
God's Blessings on you and your families through this Thanksgiving and Christmas. Len
