It's a small key 8GB for USB2 port, so neither quick nor made for huge files, perfect daily to take ordinary documents. It is very thin, allowing inserting it even if the USB port is cramped between two connections (in the case of the laptop of my colleague when we work together, I have to always be careful choose a fine key, so it's a real asset to me). She was immediately recognized by my PC Windows8. She's prettier, which does not spoil anything and seems solid. There is no protective cover, but for me, not letting my USB key in dusty, I have never had this trouble with this type of key.
