Great mouse with blemishes ...

However, you should check at the beginning whether the built-in memory chip mouse works!
For this purpose it is necessary to carry out only the following steps:

- Install the software Corsair.
- In the initial settings to disable the mouse managerial assistant.
- Profile Management, the profile M65 store.
- Then shut down your PC and unplug it. (1 minute wait)
- After about one minute you can boot up the PC again.

This is only the case when the integrated chip, the settings can not save!

Then you should change the mouse! My first mouse had this error ...
