The card works perfectly, no complaints on that. Although I did not encrypted tests on the effective transfer rate, this card saves me 10 RAW shooting 10sec 15sec included against an SD Sandisk Extreme Pro UHS-1. In short it is logical given their speeds. As against the packaging is a simple vaguely padded envelope. And the plastic mold in which the card lodge contains a place for a second SD card it a priori. Scotch Packaging has been clearly removed, one wonders if this is not the repacking ... In short, the future will tell me if I have any worries me. Hoping not to have to use the warranty. Only a CF is lacking to date me. And it is difficult to recover photos in this case ...
EDIT: After my first tests, I started using this card on my camera. The result of the write temporary delays and especially the inability to copy all my pictures at once. All pictures 5-10, copying stops. Behavior confirmed on 2 ordis. So, in connection with my review, I inspected this package that I found oddly rescotché. And notes with the map shows that despite being a REV B while the reference on the box it speaks with REV C. I asked for the return .. purchase from MyMemory. I await the return authorization. So beware, the source of these cards from some vendors lacking.
