To my amazement and disappointment I received a 'file format not supported' message.

Unhooked from MAC, went into wireless mode, saw it pop up in the WiFi list, clicked on it and got the message 'unable to join the network'.That was 5 hours ago and quite frankly I'm ticked

On day two or three I started getting device unavailable messages, but after a minute or so, the media connected

I also get a message "Unsupported Media", meaning my downloaded iTunes videos won't work - "This video format is not supported by the native player ...".

Will update this review with progress if I make any....but for now my message is buyer beware

Means, obsolete - as you can't charge it anymore

it worked just as advertised and just as I had expected it to work

It works as it is claimed

The drive itself is relatively small and works as it should.

Followed the instructions at support site, tried SSID with and without pwd, tried installed app as well as through the browser and also did not work

This confused me because as soon as it disconnected

When 3G or 4G is good just relay the Seagate Wireless Disk through the hotspot on the phone and you have a seamless connection to the Internet.
