I bought a Metallica Pro a couple of weeks ago and the wife and I are loving it. I have an interesting issue with the left orbit...every once in a while the ball gets stuck between the guide rail and the wall and I need to remove the glass to free it. Other times the ball rolls freely through??? Perhaps the ball nails the rail and causes it to bow out and the then ball gets stuck. Have any of you had that problem?
Also, I just got to crank it up (been there about 6 times before) and only two of the four modes could be selected?
