With its Imperator gaming mouse, Razer has created a product that has customizable comfort. For the last few weeks, I’ve been gaming with an Imperator Razer sent me and I have to say I’m so impressed I’d consider replacing my Razer Mamba with it. Razer achieves this customizable comfort by introducing a mechanism that allows you to slide where the thumb buttons are on the mouse. As you can see in the picture illustration on Razer’s website, you can position the buttons in the precise placement you desire. For me, that means somewhere in the middle, so that both buttons can be easily pressed from where my thumb naturally rests.
