Guys I just wanted to share some info about this item. I have just recently made me one and it seems to work. I had it at the range today and it seemed to do the job. It makes you approach the ball from the inside instead of the outside. Don't spend $60 on this thing. Go to Lowe's or Home Depot and buy thte PVC and make your own. Here is the website so you can see it to build it!
