Once you own one you will understand that you can NOT live without it. So you want to double up on backups and backups of backups. Almost anyone on this board that has an empeg also has a backup for it just incase it gets stolen or damaged. If this is the last and never to be made again then of course that's why everyone is purchasing several backups. Myself just getting 2 more, 1 for the wife and an extra backup for either hers or mine.
