It arrived promptly and the box and belt are great. My only critical review and why I gave it 4 stars is i wish it would alert you when it starts and when it turns off. When its on you and you hit the power button you cant tell if its on or off unless you look at the screen and even then, the first few times I used it unless I saw the red glow I couldn't really tell. Outside of that small detail it seems to do well.
