Great Price [...]

I only shoot in "RAW" so the SanDisk 4 GB cards were becoming a hassle because I fill them up so fast especially when I am shooting wildlife; This 8 GB made it less likely to miss another shot while changing the memory card! Never had a problem with any of the SanDisk memory cards during the more than ten years that I have been using in all kinds of weather & tough situations!

Worked for a day

This card stopped working the first time I used it. [...]! I will pursue directly with Sandisk.
