The card worked for about 20 pictures then started giving errors to be formatted. I formatted to no avail. I called the company I bought it from who then referred me to Transcend directly. Contacting them directly is impossible!!! You get no response. My card is currently on it's way to Transcend and hopefully they will replace with one that works, although I will not use it for anything super important.

I purchased 2 of these cards for a new camera I purchased as a gift for my wife. I have been amazed at the number of high res photos we can store on one of these card (about 4000). They are also fast enough for us to take HD 720 video with the camera (about 9 min.). They have been excellent.

I was initially satisfied with the item, but it failed completely less than six months after purchase, with sporadic use. Since I'm outside the US, it's cheaper for me to buy a new card than to pay for the kind of shipping that would get the item to the manufacturer in the time limit set by them to return it after a request is opened with their customer support service.

I have used this in both my Canon Rebel XSi and my Samsung point and shoot camera and it works great!

Bought 3, all for Cameras and all worked as expected. Shipping charges were very high (I guess thats how they get part of there money back) would buy again.
