Pros: Works as expected for my SD formated Canon sd630 camera.

Cons: None

Overall Review: As the owner of a Canon sd630 camera, I was suprised to discover the cap at which sd card were created which is 2GB for most manufacturers and 4GB with Transcend. This 4GB card gave my camera new life for at least a few more years before I feel the need to by a new SDHC formated camera.
