One thing to note for people using this on a lap top is that the receiver for this sticks out at least a half inch (much further than the tiny Logitech ones). This is fine if you're using it on a desktop or want to take it out everytime you move the computer but if you're looking to keep it in your USB port while you cary your lap top around I wouldn't recomend this set.
In for two for home use! I use one of these at work and they are decent.
But like the previous poster mentioned, it is probably best suited for a stationary computer like your desktop or maybe an HTPC. It is not a nano USB receiver, so it sticks out and you're just asking for it to get bent or possibly broken if you aren't too careful when using it on your laptop.
