I usually write longer reviews, but in this case, with a brief comment will suffice because this is not a detailed analysis but a simple note discussing a bad experience with a Transcend 16GB Wi-Fi I bought in late July 2013.
Having taken a look at the options available (Sandisk Eye-Fi, Toshiba Transcend AirFlash and Wi-Fi), the best option seemed Transcend, so I decided to get myself one.
Transcend 16GB Wi-Fi. A bad experience.
The first moments were a bit disappointing: the card works as a Wi-Fi server and can connect up to three devices, very intuitive to set up, but a few minutes later I could see the photos shot on my Nexus 7 and mobile, thanks to the Android application. In a few minutes, I could see them on the laptop with Windows 7 but here came the first major problem: not only does not transfer RAW files with ease, but to photos download to the computer has to be ONE by ONE. There is a web interface that connects to the card, but you can not automatically download the pictures to your computer. This would streamline the work flow when we are shooting in the studio. I contacted the technical support team to confirm this software flaw and they did.
However, the card was relatively affordable (about 45 €, shipping included) so the profitability could come by the card capacity to transfer directly photos to the cell phone. I was mistaken. That evening I took my EOS 5D Mark III and the card to a beauty event, and suddenly, the card locked my camera. It could not read the pictures and I couldn’t shoot. I had to restart the camera and remove the SD card. Photos are not lost and did not lose the work done that day, but if it was not because I had a second memory card, I’d had not been able to work. In any case, when I got back home, the SD remained unable to work, so I decided that my new SD Class 10 would be returned.
As a commercial photographer I rule out the use of this card and I do not recommended neither for amateur use. The odds that this is only one point of failure are high, but if a professional photographer can not rely on his memory card and this one not only does not permit significant function (Wi-Fi transmission) but also did not you allow view photos in the camera, those are determining factors to qualify as a bad product.
