I found that this had some good/bad reviews online. I've used it a little bit and haven't had any issues. Some said that the USB adapter made it really tough to get the card out after you transfer files, but I didn't have a hard time with it at all. Seems to be stellar, performance wise. One thing is that I'm not sure why this says it is made by GoPro, as it is made by Lexar and there are no indications of it being from or by GoPro.
