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.

You can look it up on youtube, there's a video which explains how you can fix it but you'll need to physically open up the mouse and void the warranty.

Con Distracting lights, wich can be turned of this can be done trough the Synapse software
Although the lights on the mouse look nice, they may bother or be distracting to some people. If they are too distracting, they can be turned off but that does require proprietary software that many do not like having installed.

Con Software issues
Using Razer Synapse causes slower boot up times as well as forced online sign in to use which is just a cheap attempt at an always online DRM.
Con Middle click dies way too fast
Several users of this mouse have complained that the middle click doesn't last long, in some cases not even 1 year.

Like all of razer's mice, this one has a rubber coating. Which means that it's hard to clean, will drip oil after long period of disuse and generally less comfortable than hard plastic.

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.

The Zowie EC-1 is no longer manufactured by Zowie but it still can be found on eBay and Amazon from third party sellers.
