The card for 3 weeks working with me now in a Canon EOS and doing there exactly what it should: She pushes in seconds the captured images as jpg files (as it also stands in the description and instructions) on iPad or the iPhone. The transmission speed is quite sufficient for me (about 3 seconds per 12MPixel image) and allows me to quickly and volatile Check the recordings. For more she's not there. The Raws I read then at home after a rest in. Every now and then the wireless connection breaks off short ... but that seems to be more a problem of iDevices me ... I think that's certainly not bad.
The processing speed of the card is also perfectly adequate for my EOS to normal Class10 Cards I notice in use anyway no differences, but suppose so even photos on.
