Pro Ergonomic, accommodating shape, especially for those with big hands
Though it may look tame, the mouse’s shape is quite ergonomic. Its subtle curves help your fingers position themselves while also allowing various grip types. For the same reason, the bulge of the mouse is located strictly in the middle, making it accommodating for the most amount of people, and even more for gamers that have big hands. Nevertheless, it may be more suited for palm grips because of the subtle curve at the right side which provides support for the ring and pinky fingers.

Pro Includes a set of thumb buttons

The mouse has a smooth plastic coating that doesn’t feel slippery. You can easily hold the mouse with a comfortable grip even without the rubber sides.
Pro Some customization options
The EC1-A has only a few customization options, all of which are sensor related. It is possible to change the lift off distance, polling rate and the DPI settings (400/800/1600/3200).
Cons
Con Far side buttons can be pressed accidentally at first
The side buttons on the far side (i.e. right if you're right-handed) can easily be pressed when the user simply tries to grip the mouse. This can be mitigated with practice.
Con Slight inconsistent positive acceleration at all tracking speeds
Is lessened on hard pads, Steelseries recommends a 4hd/9hd as the mouse was made and tested on it. Most people don't realize the acceleration until told about it and there are numerous professional cs go, Lol, dota, and starcraft players who have no problem with or don't notice the acceleration.
Con All four buttons are hard to integrate into daily usage, but they are not always necessary.
Con Mouse wheel can be a little finicky
The mouse wheel tends to sometimes scroll up one click when trying to scroll down, and vice versa.
Con Customization options are limited due to the lack of companion software
There is no companion software to this mouse, which means you cannot do thorough customizations, such as button remapping or custom lighting.
Con DPI colors annoying and can't be customized
The scroll wheel has an LED that changes color depending on your DPI setting, but the corresponding color cannot be customized.
Con Side buttons don't register easily
The side buttons require you to press deeply before it registers an action.
Con DPI switch can't be accessed during use
The DPI switch is a button that can’t be accessed while in use because it's located under the mouse.
Con The customization process is inconvenient
All Zowie mice are built to be straightforward and simple to use. However, its settings cannot be changed easily during normal use: you have to unplug the mouse and use a combination of different button presses while plugging the mouse in, which is unintuitive and a hassle to learn.
Con Not manufactured anymore
The Zowie EC-1 is no longer manufactured by Zowie but it still can be found on eBay and Amazon from third party sellers.
