I recommend READING directions when inflating to prevent any problems that others seem to be having. I have only positive thoughts about my new bosu trainer. I absolutely LOVED using it at the gym and am SO EXCITED to have one for my home gym!! The possibilities are endless for uses. It is a little smaller then the ones at the gym, but it doesn't impact its use at all.
I've included pictures, the water bottle is a 1.5 liter, for reference
