The concept is great, but the design is bad. It is supposed to be used individually or with someone elses help. The balls roll out of the tube on their own. I thought maybe it is the old baseballs I had, so I bought news ones. Same result. This product can only be used with larger balls, not what the manufacturer implies; all types of balls.
