Well, it is not to believe, but this mouse performs very, very well! They work without delay and radio positioning the mouse pointer is finely and precisely. The mouse software is easy to configure and works perfectly. Switching off is not really annoying, but (press a notch on Wheel and it is back online) getting used to, but can you, unless you're with Action Games all want to get out of the mouse, 1 Week, without using the mouse on the charging station to hang work. Price / performance clearly: Five stars
