Here is what reviewer wrote:
"The cost was less than half of what the brick and mortar stores are selling 2GB cards for.
Another reviewer was even more enthusiastic:
Of all my gadgets, this one is my Favorite. I use for my mostly music and photos. It just doesn't get any better than this. Plugs in any USB port and adapters for any camera and any card reader you're able to share and copy any file conveniently anytime. I Love It!!
When I inserted the microSD card with miniSD adapter into my HV30, with the latter set to make Hi-Def 1920x1080 stills, the camera informed me that there was enough memory for 1400 images.
