More than enough resolution at 5700 dpi. Glides accross my 1200 dpi mouse pad smoother than any mouse ive had. I like a heavy mouse so the weights that come with it are perfect. You cant beat $29.99 after the $30 rebate.
If I had to pay retail for it I might not have got it. Could use a couple more buttons on top for games.
If you can get it for the price I paid, its the best mouse you can get even if your not a gamer. Very accurate and smooth. Its currently the best mouse made by Logitech so there is not any thinking to do, just buy it.
