Like many others my vuk wouldnt work, would take several attempts to simply eject the ball. I did the dreaded redrill fix from Stern, but it wasnt nearly as scary as it sounded. Vuk works flawless now. Also had some other minor things such as adjusting the left orbit to feed the flipper instead of the sling, etc.
That said, EHOH is by far the favorite game in our home. Would buy again in a heartbeat on this one, its a winner.
