With all the benefits of its full-size counterparts this mouse folds down to just 60% of its original size, making it easy to store and transport. Adjustable DPI also allows you to customise the sensitivity and work on a variety of surfaces without the need for a specialist mat. 2.4GHz wireless technology means there are no clumsy wires to get tangled in you bag, instead a USB micro-receiver is conveniently stored inside the mouse between uses or can be permanently left in your laptop or computer. This is a great solution for those who work on the move as it provides the luxury of a full-size mouse instead of a laptop track pad, but without having to carry a bulky standard mouse.
