Not a bad product at all. I got it for my blackberry Z-10. I had to format it through the phone's software, but afterwards it worked like a charm. A couple months on and no problems. Class 10 and 64 gig, so I have no complaints. Only reason I didn't give 5 stars is because it isn't particularly outstanding in any way, but it is a pretty simple product. Does the job, no problems, good to go.
