Pros: 4 years ago I bought this keyboard and mouse combo and a year later built my own desktop gaming rig. I reused this mouse/keyboard rather than buying new because I was confident it was a good choice. 3 years later (4 years after I bought the combo) the USB dongle has just now died. I think it's really rare for a wireless dongle/keyboard/mouse trio to last 4 years, so I'm really very confident in recommending the purchase of this item.
Pros: Where to start? I'm a very heavy computer user, on average i spend about 5 or 6 hours per day on my computer. Of all the keyboards and mice ive used over the years, this set stands out from the rest. the subtle shape of the keyboard, the sufficiently sized yet not obnoxiously large wrist rest, the tactile feel of the keys, everything about the keyboard adds up to a flawless victory.
Cons: I have only two problems with this mouse and keyboard set. One, the F1 to F12 keys have the labels in tiny little blue lettering directly above the keys themselves. The second concerns the mouse, where the scroll wheel has no clicking action or resistance at all. Will this isn't a big problem when it comes to regular usage, during game play when using the scroll wheel, it becomes very difficult to use accurately.
Summary: Also, the escape button is the same shape and size as one of the shortcut keys, instead of a regular full size key. I've found this a bit annoying sometimes, but it's not enough for me to knock an egg off for. Just keep that in mind though.
Pros: Well, the design is really excellent. I was looking for a low profile wireless keyboard with a full set of keys. While this is hardly an Apple keyboard, it is still very thin and looks nice.
Cons: I guess the biggest con would be the lights. There aren't any lights to let you know if caps lock, num lock, or scroll lock are on. A little alert flashes on your screen in the bottom right corner, but it disappears after a couple seconds. So far I haven't had any trouble with that, but I'm sure some people depend heavily on those lights.
Summary: Only bought this as a replacement for the a previous keyboard as I had inadvertently broken the USB receiver. As you cannot purchase these separately ( due to the frequency being set for each keyboard) Just as pleased with this one as the previous.
