This is 100% spot on. I have a tennis tutor that a relative gave to me it's like 20 years old and runs like new and I've changed the battery and everything is built simple and efficient. I've also talked to James and Ron and their customer service is the best I've ever experienced.
I have a friend that is looking for a machine, it can't be the bigger plus as that doesn't fit in their trunk so we were thinking of the tennis tutor machine with remote and oscil. but I'm left wondering if you crank it to 85mph how does the ball stay in with no spin?
