Really cheap ($80)
Plug and play.
3 year warranty.
The usual awful instructions. As usual, there is always some quirk in getting non-Apple products to work with Mac OSX. It took me about 45 minutes to get it going.....but saves $220 compared to a Time Capsule, and much longer warranty.
A way cheaper way to back up versus Time Capsule. My last TC detonated after 15 months. This is new.We shall see if it is durable
