I bought this mouse twice for our netbook, but unfortunately broken twice! The mouse of the brand Trust had dropouts after 6-8 weeks in use again and again. And now after about 6 months, unfortunately, nothing works! At the very first mouse, there were problems, but they held "after all," nearly 18 months! She was of the size and shape very nicely for our Netbook, the quality is unfortunately as already written poorly. You realize then just well but that will cost you just over 10,00 Euro!
