I want all the pros and cons of not again ruminate all, so I limited myself to say that I love this card! For the price you get a great auxiliary means to and easy to look at photo shoots quickly photos to get the card from the camera without any time and to import to the computer. I save the "real" photos on my CompactFlash card, and on the Transcend SD Wifi come small previews (size S2 in my 5D3), but which can be transferred quickly still almost full HD resolution have - sufficient for a quick review, or to present it directly on a Tablet lined up to.
I am of the map so excited that I even wrote a separate Node.js application that automatically fetches new photos from the card and displays them in a Web interface. Perfect solution if you have somewhere lying around a monitor / TV and a Raspberry Pi joins it. Github: "Wipho"
