The Rosewill RKM-1600RF uses a 2.4GHz frequency-hopping spread spectrum (FHSS) wireless signal with adaptive frequency-hopping (AFH) technology and more than eight million ID's that improves resistance to radio frequency interference from other 2.4GHz wireless signals such as wireless LANs, cordless phones and Bluetooth devices. This technology is also inherently more secure than fixed-frequency wireless since it is difficult to intercept the random, frequency-hopping signal using a narrow band receiver.

The RKM-1600RF set consists of a 109-key multimedia keyboard, switchable 800/1600dpi laser mouse, nano-sized USB RF receiver, multi-language user manual and three AA size alkaline batteries. Rosewill claims battery life of up to 12 months at an average four hours per day through their power-save operation. The user manual initially appears to be quite extensive however only four pages are actually transcribed in English, the rest of the guide is comprised of pages of alternate languages. It basically only covers battery installation, initial setup and use of the five multimedia keys, with a single page reserved for troubleshooting.

The mouse is a five button style that utilizes the typical left/right and center scroll wheel, with two side buttons for forward/back operation. It has a very high arch front to back and is noticeably shorter than the average mouse. My hand easily overhangs it completely, touching the surface of the desk with the tips of my fingers and heel of my palm. The main left/right buttons are painted with a gunmetal metallic finish while the center scroll wheel and side buttons are in silver. The gunmetal metallic color is continued on the rear half of the mouse under a clear, glossy cover that features the Rosewill logo at the back. Although the clear exterior is smooth, the underlying colored section is faceted with triangular shaped sections that catch and reflect light.

The primary buttons have a very light touch and an almost matte appearance that suggests the finish may wear off the plastic over time. The scroll wheel has a shiny chrome like edging with a rubberized center track and ridges that provide an anti-slip finger grip. The wheel, like the buttons, also has a very light amount of resistance and not much distinction between steps. The side buttons reside above the natural thumb rest which will aid in preventing accidental presses. The bottom of the mouse reveals three small glide pads, an off/low/high switch to select dpi resolution and the opening for the laser pickup.

The keyboard, unlike the mouse, is slightly oversized, with an extension for the multimedia buttons and a small palm rest built in. The top surface including the keys all have a matte black finish except for a glossy insert along the bottom where the Rosewill logo resides. This area will receive the greatest amount of prints and dirt/oil from your hands so it won't likely remain glossy for long. The key layout is fairly standard for a typical 104-key with the exception of the five multimedia keys placed vertically down the left side. These buttons give the user control over next/previous, play/pause, and volume up and down.

Underneath the keyboard we find two fold out risers along the top edge and two rubber anti-slip pads at the bottom. There is also a cut-out with a slot for the USB receiver where it can be stored when not in use. The receiver is the smallest I've seen; most of the length is comprised solely of the USB connector itself. The electronics housed in the end extends only a few millimeters from the USB port, which is great for keeping a low profile but can make retrieving it from the port a bit of a challenge. As Rosewill states, it is a "plug-n-stay" receiver, meaning you plug it in once and leave it in.
