improved but still not perfect

having had the previous generation wired evolution but I note, however, the click is very marked
the top is too sharp for my height certainly big hand is perfect but I often hang when placing my hands off the keyboard to the mouse.
side since independence to do my purchase I have not yet changed the batteries but it is only 15 days! So to watch
no visibility dailleurs about it and it is a pity having to wake up the mouse with a click rather than simply moving bothers me a little.
I hope it will last longer than the first, which dropped to nine months after the wheel is part spin.
