I bought one of the 32GB for my Galaxy S4, and another for my Canon T3i. It works no problem in it, detected and formatted out of the box.  SanDisk is one of the most reliable card manufacturers in my opinion. I've gone through and sold a lot of cheap/lesser SD cards throughout the years, and almost all manufacturer has their failures, but to date I haven't had any issues with SanDisk. I've bought this same card for my wife and family members (everyone has the S4), and so far there's been no issues. I use mine heavily everyday, new music and movies, and after 6-9 months haven't had any failures.As far as speed goes, using `dd` on a USB3 card reader I recorded almost 14MB/s write speed and 33MB/s read speed. Making it by far the fastest Class 10 card I've had. They do sell &#34;Extreme&#34; versions of this card which are even faster, but most integrated devices won't see the speed increase benefits.
