Worked as expected in both my Blackberry Z10 and my HP laptop and is plenty fast - writes at around 9.5MB/sec, but reads so far on my PC that I can't get an accurate number for the speed. I gave it four stars because the write speed falls a touch short of the Class 10 rating - it's honestly not enough to be an issue for me, but people who need the speed in a camera might be slightly disappointed. However, the capacity and price more than make up for that in my mind.Also, makes a great store for content in my Blackberry!
