For wireless keyboard/mouse combination, I think this is a pretty good buy. Over the years (I've been a programmer since 1964) I’ve been through a fair number of keyboards. These days they are all generally made the same: a thin sheet of plastic with conductive ink printed on it, covered with a second “spacer” layer of plastic with holes in it, and finally a third piece of plastic with conductive ink. The keys press the top sheet of plastic down to make contact with the bottom sheet. In time, the conductive print can wear, especially on frequently used keys like E, S, T, etc. You start having typing problems. As a retired engineer, I have more than once turned the keyboard upside down, taken all of the screws out, opened it up, cleaned the conductive ink, and put the whole thing back together again. When this fixes the problem, it usually doesn’t last very long. So, keyboards don’t last forever and have to be replaced. I happen to think this particular keyboard/mouse combination from Logitech is a pretty decent product for the price. It sets up easily and has an inconspicuous USB wireless receiver which you can plug into your system just about anywhere and it does not get in the way. Remember though, if you’re a gamer and want a smart and illuminated keyboard, you pretty much have to buy a wired USB keyboard as that’s where the power comes from. I have a couple of those too.
