Almost perfect, because fast and stable reader. Sandisk 32GB SDXC UHS Tested with 1 card in a MacBook Pro mid 2011. The cable has the optimum length of Computer on the desktop and is very stable. Rubber-coated base, non-slip. The front access LED is quite bright I can test it only USB 2, which is why I prefer to save my information for performance. for me the reliability was important. Would the card slot vertically centered, the card could also take out without lifting the machine, but he is actually intended for the housing with multiple card readers. 5 stars I find justified, especially because of the low price and flexibility.
