Teacher: Now, understand the problem? Solve this instance: Nice player except the microSD card fails to be recognized anymore. The problem isn't the card (I've tried several), it IS the Player. The disappointing machine just fails to recognize that it even has a card slot. The expansion card slot is meaningless. And what with an appalling 90-DAY WARRANTY, you can see Sansa has little faith in their own products. It is really to be looked at as disposable. Get it really, REALLY cheap, or get something else. The rest of the machine operates fine and it pretty reasonably intuitive. But....but, the expansion card issue is a massive, strange failure. I wouldn't recommend this (or perhaps any SanDisk product. This just SHOULD NOT happen.
