Item arrived by Regular mail Quickly. Have several of these from prior SONY Camera Purchases... Good Price for the item just wish they offered the SLEEVE that is NEEDED to use these outside the camera... Great for Storage and for transferring pictures/data. Unless you have MORE than 8GB of Memory in your Computer this is the ideal size. Although the 8GB is great for more storage, The system will lock up trying to download the pictures/data because of the Lack of system memory.
