Great device - works with multiple Windows and Mac OSX computers connected to external 1TB drive. Declares itself on ZeroConf/Bonjour, so Mac's just see it.
Beware - I purchases two of these devices - they both have exactly the same MAC network address, which cannot be modified. So NO chance of having more than one of these on a particular local network at once.
As well as having default MAC addresses, in certain circumstances, it also pretends to be another device on the local network, causing that other device to appear unresponsive. For some reason, it responds over TCP/IP as if it was the other device, which confuses your computer. So beware - it does not always behave well on the network.
I also tried a Addonics NAS 3.0 - bad experience with NTFS - trashed data. At 3 times the price of this AeroLite, you have to question whether it is worth it! It just works (but limited to FAT32 - so no very large files).
