I have had a few of the problems listed here, but I fixed them pretty easily. It is definitely worth fixing, because for the price, this is a seriously underrated pin! One issue I didn't see here that I still have not taken care of is the hauler kick-out not having enough power to eject the ball every time. It is a small issue, and it almost always gets it out on the second try. If anyone else has fixed this problem let me know.

Also, as the OP has stated, if your ball does not make it all the way around the track, adjust the track to make a smooth transition. It should make a very smooth sound going around the track.
