We here at PocketBook-USA are thinking now about what warranty would be better for our customers: the one which is now - Limited Warranty for two years that covers basically except ADH (accidental damage from handling, i.e. - broken screens and water/vodka/beer

damaged sunken devices) or a Full Warranty for, say, 90 days, which would cover everything during this period, but after that - all repairs/exchanges would not be free (or you'd need to purchase a separate additional warranty).
In the first case you'd need to pay about $150 to change the screen, in the second you can play football with your PB or your home pet-elephant may stomp on it before 90 days expire - you'll get a new or repaired device...
Or, maybe, your variant?
