Sensei is a XAI with lights, if it's as poorly fabricated as the XAI, you better stick to the Kone+

I had a XAI and after a year it just started failing, the cord kept interrupting, the crosshair started jumping 180degrees to the left or upwards, a real pain in the ***. Now I have an Intelli 3.0 and it works like a charm, i've improved my awp accuracy and speed since I've started using it with other settings than the XAI (higher overall sensitivity, and zoom_sensitivity_ratio)

Cheers for the info chaps.
