for those of you looking for a "value bosu ball" stability trainer, this is not the tool for you. it is nothing like a bosu ball, which the picture leads you to believe otherwise. this is a basic "flat" balance disc, with a hard platform (which is seperate from the disc).
- How accurate was the sizing? totally off from the online picture
- Please tell us about the quality of the product. its not a "bosu ball" like stability trainer.....which is what the picture leads you to believe
