I bought this memory stick for my Sony Digital Camera and in summary it works great. Normally I like to go for Sony products but because of the huge price difference I thought I will give it a try and so far I have had no problems whatsoever. I also have a Sony Memory stick that came along with the camera and I cannot tell the difference between the two. However, to be honest I have not actually tried comparing the two products for the read and write times or the time to transfer the images from the stick to the computer, so there well might be a difference.
