"Couldn't be better really. Rent for 20 bucks for the entire day. John is really easy to work with. The machine worked great. You can really get your game back, and get a great workout. It's fun too, we took it out to Dolores and had a full on tennis training camp day. We kept hearing people saying how cool it was through the fence, and little do they know just how easy it is. I'll be using this again."
