In conclusion.
Even though Zowie has 40% of the market they do not have the top dog mouse, Steelseries does. They do not have the second spot either, because Razer does. The Zowie mice are spread out evenly through the list. Three of them are actually found in a four way tie in third place. The Zowie EC1, EC1-A and FK are all used by 10 players each and the mice share the third-position with the Deathadder 2013.
The number one mouse is the Rival from Steelseries who whoops the other mice by having 28 players out of 204 using it. That is double the amount of players compared to the closest model, the Deathadder Chroma, with 14 players.
In the top eight Zowie have six out of fourteen mice, Steelseries and Razer both have three each, Logitech and Finalmouse have one each. Once again Zowie are in the top. It seems as though they do not have one big model that stands out but several models that are popular.
Steelseries has one mouse, the Rival, that dominates and two that are somewhat popular.
If you count the different releases of the Deathadder mouse (the Original, 2013-edition and the Chroma) as one, Razer has the number one most popular mouse with 29 players using it. A surprising fact is that only two out of nine models from Razor are being used by the professionals.
