The S520 bundle consists of the wireless keyboard, wireless mouse, quick start guide, software disc, warranty information, USB wireless receiver and four AA batteries (not pictured). The included batteries are Duracell brand, so you know they will last a long time vs. cheap off-brand batteries often included with keyboard and mice combos or other products that require batteries to operate.
The S520 wireless keyboard is pretty plain at first glance, with a large, arched wrist rest consuming a sizable amount of the unit. There are no fancy LCD screens or backlit keys here - but at this price point, you really wouldn't expect that. On the bottom of the unit, we find four rubber feet to hold the board in place on your desk. Two extendable feet are located near the top, should you prefer to type on a slight incline. Logitech thoughtfully included a sticker labeled "Connection Assistance" to help users connect the board to the receiver. A battery compartment and connection button round out the items of interest on the bottom of the board.
The buttons on the S520 are what I would call low profile. Logitech made the F1 - F12 keys dual purpose using a function key, much like what you would find on a notebook PC. You can also see that Logitech printed shortcuts on specific buttons, used in conjunction with the Control key. Using shortcut keys consistently is good computing practice and can save you a considerable amount of time. Speaking of shortcut keys, there are two additional keys on the upper right side of the board: calculator and PC power. Neither of these are anything new, but I do like the position of them, especially the calculator button, which is conveniently positioned right above the number pad.
Along the bottom of the standard keys is a set of specialty buttons: three zoom buttons on the left, three audio buttons near the middle and three media buttons on the far right. There is also a battery level indicator just below the arrow keys.
