The A4Tech X6–287D GLaser Mouse is the world’s first optical mouse that is designed to work on shiny or glass surfaces. How do they do it, we hear you cry with astonishment. Well, it’s all down to the dual focus lens design, which does all kinds of clever things with reflection. That wasn’t too technical for you, was it? Anyhoo, it’s Korean, comes in pretty colours, has a double click button and costs money. OK?
