There is nothing more to say. They work great in my 5D and 5DII. I bought them because they were quite cheap and for the money this is a good card. They're fast enough for the type of recordings I do, and they're reliable. I bought 8 of these to add to my bag for when I'm in a pinch and I run out of storage. I have multiple Lexar 400x cards that I can't tell apart. I've always been a late proponent of extra large memory cards. I'd rather have 10 small ones than one large one (you know, it's all "don't put your eggs in one basket") and these Lexares are perfect for that.
