There is a learning curve in the beginning. It is intuitive and easy once you get the hang of it. You touch where the racquet was, what kind of shot, where it landed, and what shot outcome was like winner, forced error, etc. Worth the $50!! it is an amazing program. You get faster with practice and you need to stay with it to get proficient. Then you just need a good viewing seat to the match. Extremely helpful to players, parents, and coaches. Love the stats and scatter diagrams!
