It is SO light--I love it. Am still awaiting the airbelt which will only give me more freedom. I only weigh 140 lbs and am 65, so trying to carry the 10 lb. portable, then the 7.5 lb portable was too much for me. I am delighted w/ the FOCUS" (Originally posted July '13)

A great help with my dancing
I have had my focus portable concentrator for 2 years now and I would not want to be without it. I am an active ballroom dancer so I just clip it to my belt and away I go. I could not have contemplated dancing with a cylinder on my back. (Originally posted December '13)
