We had the Pocket Radar Ball Coach and loved it. But when I saw the Smart Coach in action I had to have it. It has so many uses. From exit velo testing to pitch speed and pull down speeds. But it's really helped us with rehab throwing. If you know what your kid throws normally, do the math figure out what percentage they should be throwing during rehab. Then set up your Smart Coach and let it do its thing. And Maximum Velocity Sports is top notch. My Smart Coach was my first purchase from them. Received my order quicker than was expected and I've since went on to order more stuff.
In short, if you are on the fence about ordering the Smart Coach and ordering from Maximum Velocity Sports, don't hesitate and just order.
