For any of you who have a digital camera, it takes some sort of SD or MS card, and they are small, easy to carry around and very easy to use. This tiny Lexar SD card is one giga byte and it holds about 170 pictures, depending on what camera it is placed in. It has a tiny slide on the left side and when it is down it locks it so that when you put it into a camera the camera can not take pictures and place them on it, push the slide up and pictures can be stored on the card again. I like the lexar brand, the products always work like the packages say they will work and I am never mad I got something else. On the back of the card there are five little gold sections that connect to the inside of the camera, if any of these are broken or bent into some weird way then the SD card will be broken, I shoved another one of my SD cards too hard into my camera and one of those things snaped and now I can't get my pictures off and it wont connect to my camera at all so I can't ever use it again.
