I don't own one but a good friend of mine does. First thing you have to remember is the name of the company, Homepin, and that is exactly what this game is intended for, the home, it is not really a commercial quality game intended to be beat on 10 hours a day on location. That said it is a decent game with some "interesting rules", again, not what we have come to expect from the other manufacturers. They have offered a retro fit of a metal ramp to replace the plastic one, and this is an absolute must, makes the game much better, and now feels solid instead of flimsy. BTW, the game itself is quite well built!
I'm not certain what the price difference is between a TB and a Stern Pro, but I think there is a niche for this game for those who just can't get to the Pro price point.
