I bought this for my 8 year old son to help him learn to hit and throw better. He loves it. He wants to use it constantly. We also take it to practice with him and the whole team uses it. It was a little hard to fold up at first but after several times it get's easy.
I needed something to help my son with his hand eye coordination. He was always looking at third base (not watching the ball) as he was swinging the bat, with the tee he would have to watch the ball as he was swinging. I can honestly say he has improved using this product.
