Relentless_1

Scroll wheel is fine no issues. Battery life i would roughly say 12-14 hours of use with 15 min sleep mode and rgb on.

It would be nice if Corsair acknowledged the problem that everyone is having. Simple we are working on it would suffice.

In order to update the firmware. Click on the update the firmware while the mouse is not plugged in to the pc .It will give you a message in red letters that you need to plug in your mouse. Then connect the mouse to your pc with the cable provided and then click update again.That worked for me.

Was able to update the firmware after a few attempts. There are other problems. 1.After dark core is awaken from sleep mode it stops responding or doesn't load the default profile i have to manually close CUE software and restart it in order for the profile to load. 2.At times i get input lag and the receiver is 2 inches away from the mouse. 3.The mouse doesn't turn off the rgb light when it is charging the thing will keep going until you unplug it. 4.Constantly loosing connection with the bundle. For the premium price that Corsair charges maybe these things should have been resolved before the product was released.The design of the mouse is great but wont deal with the nonsense for too long.
