[citation][nom]ohim[/nom]I`m still using my 9 year old MX310 and besides the color fade on it, it is working as perfect as the first day. Very impressive mouse, i would be looking for a similar precision mouse in the wireless series for my laptop but i don`t know which one might be up to the task.[/citation]
But I found the recent mice from Logitech had lower quality. I had one used for many years until the mouse button was broken which was fine as it served me so many years. So I bought another one, about a year of use, the sensitive of the mouse reduced significantly and became erratic. I was hardly able to control the cursor. I have to move a much greater physical distance to move the cursor a bit on the screen, initially I can "fix" it by banging it on the table but eventually the problem became permanent. Since, I bought another one. Occasionally it has similar problem, I can fix it by banging the mouse on the table, so far it is still OK after almost 1yr.
