Saw this in store when browsing - a 5 button wireless optical mouse in a safe Zebra design.
It's the same price online but you have to pay P&P which makes it nowhere near as good value.
Ergonomic mouse with grip-friendly, rubberised surfaces. 5-button mouse with clickable scroll wheel. DPI selector button (1000/1200/1600) for quickly adjusting your mouse speed. Nano USB transceiver. Battery: 1 x AA/LR6 (included). Size: 105x73x36 mm.
