This is a quality keyboard and mouse set. They are both USB, and install very easily on every computer I have treid which includes two desktops and a laptop. The keyboard has several programmable buttons that you can use to open differant folders, or run differant things if you want. It also has a volume controle right on the keyboard which is nice. The other nice thing is it seems very durable. I have three kids that have knocked it off the table I have it on, and i have spilled several things like drinks on it and it still works just fine. The only thing I personally don't care for is it is not an erganomic keyboard, but that is not a huge deal for me as I don't really type long things very often. If you are in the market for a new keyboard/mouse set I would highly recommend this one.
