Have this mouse purchased with the Logitech Presenter R400 and was not disappointed. The free processing is good, the mouse has a pleasing shape, covers a large area and it works well on different substrates. The small USB stick is great and may even remain plugged - you take it out, you should but considering the size mini also have an eye on ;-) For this purpose, the mouse has an on and off switch for power saving. It is perfectly adequate for the daily work and does this very well.
Result: price / performance absolutely correct and therefore buy recommendation.
