I have been using the Razer DeathAdder Chroma for around 6 months, and I love it. It is the best mouse I have ever used (because it is my 3rd ever mouse, 2 being $20 Logitech ones). Now I hear that Razer announces the DeathAdder Elite, and the reviews are all positive. My question is: should I upgrade from the Razer DeathAdder Chroma?
