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.
