Here is my Silent Partner Edge Star. I use it twice a week. I love it.......for what it is. I think the unsatisfied people have unrealistic expectations. People! It's a machine, it's not a person. If you want an easy wonderful way to practice your ground strokes....this is it. Take 15 minutes to set it and forget it. You are done adjusting forever. Get the remote and larger battery. Put it on the baseline, fill the hopper, walk to the opposite baseline, touch your remote and hit away! It is perfect for this application. You can bang forehands and backhands all day long. Sweep or stay in the same position. It is perfect for this. Now, if you are wanting a session of hitting lobs, volleys, and ground strokes.......then call a friend! Otherwise you will be spending too much time constantly adjusting the machine to lob, then re setting it to volley, then resetting it yet again for ground strokes. This will be a long tedious and frustrating process. Just not worth it for me. Get a nice ball hopper that holds enough balls. Enjoy your machine, it's a great supplement when a hitting partner isn't available. Just have realistic expectations.
