Positives: With space for more than 3,000 RAW photos no more replacement cards are required for most events if you want to entrust all photos a single card. The price is very favorable.
Negatives: The indicated speeds are rarely achieved in practice. A full cache of 7D (22 RAW photos) requires 30 - 40 seconds (ie about 1.5 s / photo) to be completely written to the card. In a Transcend USB 3.0 card reader to read with 52 MB / s of the map. The write speed is in both the camera and the card reader 11 to 16 MB / s - from 60MB given here / s can at least be no talk with my hardware.
The package came relatively quickly within 3 days from abroad (there were British vouchers in). All in all a recommendable value for money if you do not expect superior speeds.
[Addendum of 12/12/2014]
Two years after buying my card has experienced approximately 30,000 raw photos and much moisture, but shows no weaknesses. I obviously got lucky with my copy.
