I have been a massive mx518 fan and my last mouse was the 3rd mx518. However since vista /window7 logitech mice has been extremely unreliable and I was crippled with what I think mostly software issues.

problems I faced

1. if I use setpoint it would stop working randomly, it wont crash but the mouse sensitivity would suddenly drop down to extreme low mid game and stay that way

2. similar problems even if I used windows provided driver.

3. in_mouse 1/2 did not help much regarding this.

overall I am frustrated with logitech mx518, and would be happy to say goodbye to it. I am looking for a mx518 replacement which has to be reliable and wont act up midgame.

should I go for MSIE 3.0 or the deathadder or something else ? can any one provide some advice ?
