The product fulfills its function, it is in fact well connect a USB mouse / wireless / SD card and enter it on the shelf, so good product, but the finishes are poor: the SD adapter is perfect, but the USB is lousy, it is necessary on mine really force to depress the USB key, and to remove what is even worse, so be careful if you have sensitive USB key! Then even the Samsung, it's still a bit expensive for what it is. But hey it fulfills its function that's something!
