The belt is not wide enought for people like me who sometimes while running bear a couple of inches to either side. I have to be constantly aware that the belt is thin and cannot take my mind off it while using it. I have stepped on the side surface a couple of times and believe me it is not fun. But everything else is just swell, the display is good, it is foldable, it is strong and delivers good its purpose. Great equipment for smaller people like my wife... she loves it.
