SO ridiculous. Exact size. I have tried several trainers, and sweat belts and nothing holds quite like this. They are somewhat narrow at the tops and I notice his pinky toes falling over the edge here and there, but it doesnt seem to bother him much. Just generally not as durable. Overall, a shoddy product. Buy it for the excellent radios for wi fi and cellular communication. Not too hard to figure out how to insert the batteries, there are green arrows "pointing" the way. Turning the wheel will raise or lower voices and not affect the in-game volume. This is an awesome product!
