When it works this mouse is excellent. It's comfortable to use, the buttons are in all the right places and the scroll wheel is nice and easy to use. Unfortunately this is the second mouse of this model I've had that I've had to return (The first came from a different retailer). The first one lasted 10 months before the scroll wheel double click stopped working (It would click but wouldn't register with the PC). The second one lasted 3 weeks before the scroll wheel actually broke on one side and caved in which made the scroll wheel stop registering with the PC. I'd recommend staying away from this particular model and either trying a different Corsair model or another brand.
