Excellent cosmetic and working condition.
This is the easiest wireless and backup solution available for your Mac. Airport Utility makes network configuration a breeze, and Time Machine makes backups even easier. While sold by Apple and optimized for Macs, it can be used with PCs or other computers.
This is the later model that supports simultaneous dual band wireless-N networking (simultaneous is a must if you still have older devices and don't want to kill performance of faster devices). The internal hard drive provides 1TB of storage for backup or general file server.
Like all Time Capsules, you can connect external USB devices like printer or hard drive to share on your network.
