I got this a couple of years ago after I had my son and never gave it a fair chance and about 9 or 10 months ago I started using it almost on a daily basis. It really has made a huge difference, I use it roughly 6 to 8 minutes a day which doesn't seem like a lot until you try it. It has made a huge difference in the top and sides of my abdomin and also has made my overall waist more narrow I love using this along with other exercises in my everyday routine.
