Summary: I bought this card as an upgrade to the memory in an expensive media player I had purchased, and have to say am very pleased with the results.
Summary: I bought two of these cards for use with my Canon HF100 video camera. I have other class 10 cards which work just fine with this camera, in all modes.
Summary: this card will not work in Nikon products... you really do get what you pay for, I bought it and had to return. Nikon suggests using only name brand cards.
Summary: I am very pleased with this product and its functionality for high speed hardware. I am using it in an Android laptop and on my PC alternately.
