This thing is awesome if you own a pingpong table but don't get to use it often. I live with someone who physically can't play a game against me so my table went unused for weeks at a time. I was a bit iffy about spending this amount of money on a robot and a net to surround half the table but I am so glad I did. I use this thing almost everyday. I don't know if it's actually making me any better but it's fun and that's all I care about.I do have a couple of complaints but not enough to remove a star. First, I don't like that the controller is hard wired to the robot. The wire is plenty long enough to run it to the other side of the table but you can't disconnect it from the robot like you can the power cable. Which sort of leads into my next con: mounting the controller isn't super easy. I ended up building a little bracket that hangs under my table and holds the controller. I suppose you could velcro it to the back of the table but I was concerned about running into it during play. I'm super happy with the bracket thing I built but it just adds another step to take this thing off the table since the controller can't be disconnected.Overall, I really like this thing, tons of adjustment, holds about 120 balls, has never gotten jammed and most importantly, allows me to play ping pong by myself.
