Teejay,
If you value your Domino, I would get Midge or Major to demonstrate it. The last time I used mine when Midge was present, I tripped over the cord and the Domino fell off the bench onto the concrete. Remarkably, it stll worked perfectly. But I am a klutz if I have any distractions.
Sorry to hear that Ivan won't be there; he always looks impressive in joint-testing photos:D
