Did exactly what I needed it to. I sometimes take my work home, and due to the security requirements, I cannot use my personal computer to access our network remotely. I have to use the laptop they provide me and I hate typing on a laptop computer. This allows me to use my mouse and keyboard from my personal computer, as well as my larger monitor, without having to swap out cables each time. So far no issues with it.
Pros: The hookup was easy and, contrary to what you think, it is important that the designated USB ports are used for the mouse and keyboard.
Cons: The manual is not much help when it comes to figuring out if any software/firmware is required. Additionally, the hot key combination (2 x "Scroll Lock") actually takes 4 x "Scroll Lock". Also, a keystroke occasionally and inexplicably repeats.
