Has anyone here tried the "Personal Pitcher"?

Hey guys I've been playing baseball for 8 years now and have always dreamed of having a pitching machine in my back yard. I searched the web for a portable one that doesn't have to throw regular balls and doesn't need a whole batting cage set up. I found one product that I am thinking about getting as it is only about $160, mounts on any camera tripod, uses golf size whiffle balls (harder to hit), and i could just set it up inside a dining tent thing we have. It has everything I am looking for but i just want to make sure its not a ripoff.

If anyone here owns one or has heard anything good/bad about it, a little review to let me know if its worth my money would be greatly appreciated. Thanks!
