This is the best memory card I own. With 4GB of space, I can store hundred and hundreds of pictures on it before needing to empty it (and I have a 10 megapixel DSLR camera that stores pictures as very large files!).
It is a very fast card, too, which is great when I use the burst mode (where the camera takes several continuous pictures in the matter of seconds) on my camera.
At only $55, this card is a bargain. Never having to worry about the time it will take to write a file onto the card and never having to worry about the card corrupting files make it nearly priceless! I will not hesitate to buy more of these in the future! I would recommend it to any digital photographer: hobbiest or professional!
