Corsair Ironclaw RGB Wireless Gaming Mouse - 18000 DPI Optical Sensor, RGB Backlit, Ergonomic Design for FPS/MOBA Games - Perfect for PC Gaming & Esports (Black) - CH-9307011-NA

The biggest reason I wanted to upgrade my mouse was to get one that fits my large hands. Many other mice i have tried are just too small for me and make my hand ache as i use it for hours on end while gaming. This mouse is big and meaty and fits my hand just right. The mouse fills my palm and i can actually rest my entire hand on it without compromising its operation or my movements.- The mouse has 3 programmable DPI settings that are changed using the furthest back, middle button. There are three subtle white bars (that can be changed to any color) by the tip of the thumb that let you know instantly what setting you are in.- One of the biggest things i noticed right away is that it has very little friction between the mouse and the pad surface (using an $8 Amazon Basics mouse pad). Very easy to move and despite its large size, is not very heavy and allows you to lift off the pad without too much effort.- The RGB effects are not in-your-face by any means. the scroll wheel lighting cannot be seen while sitting with it in front of you, but this is not a big deal to me as i did not choose it for its RGB qualities. The corsair logo however, is easily visible with your hand off the mouse and is visually, very pleasing and well done.- The Corsair ICUE software is pretty easy to use for the most part and allows you to change the function of most of the buttons along with the color patterns and brightness control. There is a calibration feature within the software where you move the mouse in circles quickly and it presumably adjusts to the fiber texture and the tightness of the weave in the mouse pad, giving you better performance and accuracy. I did not experience any noticeable improvement however, but it was performing excellent right out of the box anyways.If you have large hands and are trying to find something that accommodates you, this mouse would be perfect, and it is completely as advertised. I have no complaints at all and am looking forward to purchasing more Corsair products in the future.
