I am very satisfied with this mouse, it is perfect for me, I wanted a little mouse but not too much at the same time I wanted to have it well in hand, I did not want her to do gadget, it is exactly I was looking for, it is solid, use was made instantly when I connected the USB cable, the most is that we can also scroll the screen from left to right, so good, I Highly recommend !! and she has a pretty design .... Value for money "Excellent"
