Elecom offers a new range of wireless mice, the Prumie. They’re got a new design, the USB dongle can be stowed inside, and they support 800 and 1,000dpi. Model M-P3DUR also has the “+1Button” that allows you to map up to 31 different functions with the Elecom software. Don’t dream, you won’t be able to allocate 31 functions at the same time, like a macro, but at least, you’ll be able to map pretty much any functions you want.
