Zowie EC2-A vs Razer DeathAdder 3.5G

The Zowie EC2-A is made of high quality plastic that's lightly coated to help with grip. The buttons click easily and the rubber cable is thin and flexible. All of this combined gives a feeling of quality, while also being functional as a high-end mouse.

The Zowie EC2-A delivers accurate mouse cursor movement that is essential to any gaming mouse. The Avago 3310 sensor used by this mouse is exceptional. It delivers a true portrayal of mouse movement with no jitter, acceleration or prediction. The available DPI choices of 400/800/1600/3200 are all native and should ensure an equally good performance, regardless of which one is chosen.

The left and right mouse buttons have small grooves to help fingers rest in place. The left side lets the thumb grip the mouse comfortably. The side buttons are in an easily accessible, yet unobtrusive position. The coating is slightly textured to help you control the mouse confidently.

EC2-A weighs just 94 grams, making it light enough for quick mouse movements and won't cause fatigue after extended use. At the same time, the mouse feels solidly built.

Its elegant, ergonomic design is suitable for most hand sizes regardless of the way you hold it.

It's worth noting that Zowie offers the EC1-A version for larger hands.

Although the buttons have Huano switches, which are more stiff, the shell of the mouse somehow negates this and makes them click easily, just like typical Omron switches.

There's no advanced functionality or accompanying software. There are just 5 buttons and the only settings you can adjust are CPI, polling rate and lift-off distance. And only in preset intervals via specific mouse button combinations. It's a mouse that focuses on the essential factors only - comfort, performance and build quality - all of which it excels at. It doesn't get distracted with anything else. If you think all the bells and whistles that come with gaming mice are unnecessary, this just might be what you're looking for.

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.
