The mouse is comfortable and works great, just what you want in a mouse. When we first got the mouse we discovered the driver/app wasnt up to date and we couldn't adjust the light settings as described. Upon contacting Mightyape they sought an update to the driver, and within the week the driver was updated and the mouse settings were fully functional again. Great followup service from Mightyape and Gorilla Gaming. Which is what you want.
