"Great bargain!"

I wanted a good quality micro SD for video recording my nephew's wedding. This was more than enough storage for a couple hours of mixed 720p and 1080p recording with plenty of room to spare. Video looked good for the quality of video cam.

"Keeps dismounting itself"

I had this for my smart phone and it kept dismounting itself. I did some research and found out that there are others experiencing the same problem. So, I returned this and got Transcend instead. Transcend works fine with no problem.
