I have tried it already as it's already available in Hong Kong (btw the pictures in the review are of HK too!). The main problem I had was that I need to open the app and pick which pictures to download, then it will start downloading them onto my iPad. That is very slow! I returned it and exchanged for a 8GB eyefi Pro X2. After using the eyefi speedwise it's about the same but since the eyefi can start downloading as soon as pictures are taken, it feels faster when you open the app to review after shooting. Although some pictures are still downloading to the iPad, I can at least start reviewing the pictures taken first.
