This is a great product! I have a 3 year old that is starting to play soccer and it's great for him to practice kicking the ball with, he can even do it in the house and we don't have to worry about the ball flying and breaking stuff. The waist strap is adjustable and the Velcro is very sticky. It comes with instructions that are very helpful. I thought I could just take it out of the package, put the ball in and go but you have to open the hole to fit the ball in. I tried to do it without the instructions and immediately found I needed them. Within minutes he was kicking the ball around. My 15yr old and husband also have used it. It's a great well made product.
