Highly unstable ... and does not have the functionality of its famous competitor ...

If you want to transfer photos from your camera to a tablet (I tested for Android, using the software recommended by Transcend, available in Google Play) or directly to your computer (tested on Windows 8 via Internet Exporer and Ubuntu 12.10 via Firefox) is a very useful map.
If you hope as permitted by the Eye-Fi card, send your photos directly from your camera to a computer located anywhere, or to Picasa ... go your way! The Transcend card allows this only through the connections of devices that connect them. By default, this will not be easy: the card is configured to switch to a router ... and prevents connecting to the Internet. No panic mode "Internet" allows you to connect to the card through the router you use for your Internet connection. As many know ...
Connection changes are random: and when the connection is established, it is often unstable. In short, you have to choose a mode, use and configure, and above all, do not have to change anything ...
I think use the map to view pictures as and when they are taken, and for this use, it should. I hoped to find other duties and enjoy a stable system ... so I'm a little disappointed and put it 2 stars.
Fixed: after a night of testing, I drafted the opinion above.
The next day, I take the camera. And no way to photograph! The card is locked in protected mode. I did move the latch placed sticky paper on the slide, tried to format in Windows 8, 7, XP, Linux Ubuntu 12.10 and obviously on the camera. Nothing. Card unusable after 5 photos and 30 seconds of video!
I refer ... requesting reimbursement! This card I lost enough time!
I should go see the comments (and evasive answers Transcend) on Amazon.com: either people love or it did not work In short: the principle of these cards does not look too bad . But technically, it is not the point. Conclusion: to monitor. If positive comments appear in the coming months, after updating firmware and programs, try buying.
