I have a Razer Deathadder Elite that will not change color and dpi and Razer won't send me another one because I bought it off of Ebay. I felt the mouse was a tiny bit too big for me, but I kinda gotten used to it. I don't want to buy again from Razer because they won't send me another one even though my warranty won't expire until 2019. Should I just buy another one or a different mouse?
