The mouse is very good, but when I used it with bluetooth 3.0, it kept disconnecting and it was anoying. It works nice with the USB and bluetooth 4.0, it is very silent to use, you will not hear the clicks, only the scroll, it has a normal mouse size so it works fine for big hands. It came very well packed and it took 17 days to arrive in Brazil, it was very fast! And I did not pay any taxes. I will check if I can fix the problem with the bluetooth 3.0 and I will more comments later.
It arrived very early. It was a good product as expected. Thank you.
