The remote is beautiful, but I could not plug the receiver into my (less than 1 year old) laptop. I was able to plug it into my desktop computer, which is 2 years old. The GME321R has a PS-2 receiver, my laptop is not compatible with it. Apparently the GME322R does have the USB receiver, with a PS-2 adapter included. The laser is very strong. I am now eagerly awaiting the arrival of the GME322R model :). The description of the GME321R does not explicitly state that it is not USB-compatible, so be careful to chose the correct model for your system.
