After unpacking my Michell Mycro (I've recently moved house) I discovered that the platter didn't rotate freely. I phoned Michell and spoke to a friendly tech guy and, after some detective work, he worked out that the little ball was missing from the bearing. They posted a new ball the next day (the phone call was too late to make that day's post). When I asked them how much I should send them they just said "forget it". And I thought you didn't get service like that any more.
