First it is fast real class 6 so no worries there. I used this in a canon dslr camera and a canon HD video camera to test all abilities. Works without a hitch with even the most demanding tasks. The only reason no five star is the fit and finish of the casing is not up to specs. It sticks and had to be pulled out of cameras. Tried in six electronics to make sure. The more it is used the less it sticks so that is good. Posibly just a minor manufacturing problem that will continue to work itself out. I have several transcends and this is just as good so far. The only media I have ever had failure with was kingston, and no they did not stand behind the lifetime guarantee.
