Unlike the recent gaming mouse and headset we reviewed from U.S. newcomer Trust, the DS-3250 Optical Wireless Multimedia Desktop is actually a fairly competent set of hardware. For $65, you get a mouse and keyboard (both wireless, as the name implies), each geared toward controlling the various digital media functions of your PC. If you're looking for a set of basic wireless input devices, we found Trust's set provided most of what we look for.
With no software to install, you only need to install the included AA batteries in each device, plug in the USB receiver, and then pair the receiver to each device. To make that connection, you press the receiver's Connect button, then hit the corresponding button on the mouse and the keyboard. You need to connect both devices within the same connect session, so it requires a little bit of dexterity to make sure you can get at both buttons quickly enough, but once you're connected, you likely won't need to worry about the process again.
There's not much else to do once your computer recognizes everything. As detailed in the brief manual, you can use Windows' default keyboard configuration software to make any changes to the default launch programs or to customize keys. You might want to dedicate one button for launching Windows Vista's Media Center, for example, which has no hot key in the default setup. Otherwise, you can simply plug it in and go.
Of the various keys on the keyboard, you get dedicated media control buttons, including mute and volume knobs, as well as a set of Web-browsing buttons, application hot keys, and buttons programmed to launch the Windows Calculator and My Computer, among others. We appreciate the latter two especially, since we don't recall seeing them before, but they make perfect sense. For basic typing, the standard-layout keys are perhaps a bit "clacky" but they have a responsive feel overall. It has a comfortable low profile, similar to the Logitech diNovo Edge. You can also prop it up with two snap-down feet on the bottom.
