Summary: Pros: High quality rubberized material over the entire surface of the mouse. Amazing ergonomic design. Simple, 5-button design. Feels sturdy well built. Weight-adjustment system. Mouse buttons are not too heavy/too light. Custom lighting options. Scroll wheel is accurate and high quality.
Summary: I have finally found my perfect mouse. I have medium to large hands (size 8 surgical gloves), and a wider palm. This thing feels like it was molded specifically for me. Long gaming sessions and ZERO discomfort. I love the rubbery texture. Feels near identical to the Razor material...which is a good thing to me. I like it better than the hard plastic Logitech uses. The sensor is amazing.
Summary: I'll start by saying my only complaint is that the mouse software sometimes glitches and resets to the default settings except the dpi. It only happened Couple times in a month and takes less than 5 second to fix. Because every other aspect of the mouse is so good I couldn't take a star away for this.
Summary: I've owned this mouse for about a month, and it has been nothing but excellent in that time. It is very comfy for my grip (two finger grip) and doesn't fatigue my hand during longer sessions like my old mouse did. Buttons are all very smooth to actuate and responsive. Got it used in "Very Good" condition, and there is virtually no sign of wear and tear.
Summary: I am not a gamer. I am a medical coder working from home on a company laptop. I did not even know about gaming mice until I looked on Amazon to find a better mouse. The cheap mouse was lagging and wandering to the point of slowing me down doing charts. I can code faster than the old mouse could move. I have a 2nd monitor attached to the laptop to display the chart. I input codes into the laptop screen. I constantly move between them, scrolling and entering codes.
