I bought this product to read my high speed SD cards from any machine but after traveling home test, it turns out that the product is not very easy to use. In my case (Windows Vista), if I do not eject the card and then the very cleanly memory card reader is corrupt and some lost data. Worse, even with the read-only protection from the SD card, the data is still corrupt ... I do not recommend this product if you want to read sensitive data with.
