Bought this card a year and a half ago. Recently it has stopped working with no visible damage or misuse. (I've tried numerous card readers and computers).
I would advise buying from more reputable manufacturers in the future.
I used this with a Canon 550D and it can perform up to 24fps @1080p and 50fps @720p.
Got two of these now, use one in my Cowon d2+ to double my storage and have no issues with watching video off it, no speed/stuttering issues, works straight out the box.
Also use one in my 12MP KODAK Z1285 digital camera and again extreamly fast response times for both video and picture taking and access/playback, again use staright out the box. At this price they are a bargain, buy one now!! or two or three.....
