Razer DeathAdder 3.5G vs Mionix Naos 7000

This mouse is well-known for its ergonomic shape well-suited for lefties. Its sizable groove on the right side guides the left thumb to a comfortable spot. The left side has a slightly angled surface that gives freedom for the rest of the fingers to position themselves as they please.

The DeathAdder has two thumb buttons that are quite large and easy to press without getting in the way of the grip.

Due to its curves, it feels natural to hold the mouse with a palm grip. It has a defined thumb groove on one side and an open side for your ring and pinky fingers on the other. The general contour of the mouse is curved so it feels like it is specifically molded for you hand. The mouse relies more on its shape rather than textured finishes to maintain your hand’s grip.

Although it’s an older mouse, its Synapse 2.0 software is still updated (as of Spring 2017) and allows you to change DPI, polling rate, create macros and reassign buttons. All of the options are tied to profiles. Keep in mind that certain modifications will not work unless the software is running in the background. The software also has optional stats and heatmaps that track your mouse usage. The software is PC and Mac compatible.

This mouse comes with the Avago S3888 sensor, which is decent, but doesn’t offer perfect performance. Some of its original issues can be fixed with a firmware update. Originally, it has four DPI stages of 450/900/1800/3500. However, its 1800 DPI option is native and is regarded as the most accurate one with the highest perfect control speed. If you use the updated Synapse 2.0 software, these options increase to include every value between 100 and 3500, with steps of 100.

The top of the mouse has a hard rubberized finish, which allow sweat to evaporate easily.

The Mionix Naos 7000 gaming mouse was designed for a full five-fingered palm grip. It has concaved left and right buttons to help fingers stay in place, textured sides to help with grip, and supports for the thumb, ring, and pinky fingers. Larger than a typical gaming mouse, its ergonomic shape is very comfortable for long gaming sessions.

The accompanying software allows you to rebind keys, change the polling rate, double click speed, scrolling speed, acceleration, lift-off distance, set up profiles, macros and lights, or separately adjust X and Y axis sensitivity.

It uses the ADNS-3310 sensor, it's an accurate 7000 CPI optical sensor with no angle-snapping, hardware acceleration, or jitter.

The nestled thumb rest on the left and finger cut outs on the right reduce wear and tear due to unnecessary hand movement. The matte rubberized finish to the mouse also aids in hiding cosmetic wear, even after years of use. Additional features include smooth teflon feet which allow for little wear on the bottom of the mouse, and a braided cable that protects the wire from rips and tears.

Users are able to adjust the mouse's settings easily, allowing them to control what they want from their gaming mouse.

This mouse is neither too heavy nor too light: its weight is just right, maximizing comfort.
