Summary: Had a Sandisk card forever and never had any problems but when it came time to get an extra I thought I would save a few dollars...bad idea. When I first got the card everything seemed fine, until I had about 1000 pictures on it and went to transfer them to my computer.
Pros: Nothing really.
Cons: Locks up camera, corrupts huge batches of pictures. All around bad purchase.
Pros: Good price for a basic memory card. The speed is fast enough for any point and shoot. Basic (non-HD video) recording was fine with no buffering lag.
Cons: These are not high capacity, or super fast, but given the price when they are on sale, this is a non-issue. If you need something bigger, or faster for HD video, then spend a little more money. This memory card is for basic pictures and video only.
