Before I report a warranty case, I'll ask here, maybe someone knows what the reason is or has similar experiences. I've had the pad for just under 6 months and the mouse pad just won't stay on the charging pad any more :-( I'm moving the mouse around and I'm already pushing the mouse pad half off the charging pad, even the weight of my own hand is enough to do that. In addition, I can already see the outline of the induction coil? on the charging pad...... Is this really Logitech quality and it's already worn out after just 6 months? Or is this more of a warranty case?
