Summary: I bought two of these memory cards on sale, and both are now dead. The first one lasted just about a year then started giving write errors and then quit. The second just up and quit period after about 8 months of use.
Summary: I have three of these in various devices. My last purchase stopped working after less than six months. I hardly ever write to them but use it to store music mostly to play in my tablet(s). Tried it on a windows machine, a linux machine and other tablets.
