I bought this for my nephew to clock his pitching speed, and it has been spot on every time. Within 20 minutes of using it, we were able to find a problem with my nephew's mechanics that helped him get another couple MPH out of his fastball, and he's been practicing all winter with his brother. Their mom tells me that they don't even want to play video games anymore, everyday when they get home from school they want to start tossing the baseball around with the Speedster III. Was the best Christmas present I bought!
Pros: Easy to Use Out of Box, Affordable
Cons: none
