I've recently purchased the ZOWIE EC-1 and EC-2 (which is available from Newegg) ...
Must say it's an amazing mouse, and I've used almost every gaming mouse that's good for FPS such as the Razer DA, IE 3.0 , IO 1.1 , MX 518, SteelSeries Xai...
And i have to say, the mouse from Zowie really preserve the quality and simplicity of popular 3.0 / 1.1 ... except it's even better !
The EC-1 is simply a bigger version of the mouse, its size is close to DA / 3.0 / 518... while the EC-2 is the smaller version of the mouse with size comparable to 1.1 / Xai...
Figure i'll let some people know about this amazing mouse... I was a pro CS player... and finding a good mouse has always been hard for me...and now that i have found one... i think it'll be unfair not to share !
also, the EC-series come in two different versions,
the White - features a glossy 1.1SE type of coating, which from i've heard is quite popular among gamers who tend to sweat a lot....
the Black - features a rubber coating that is similar to the DA coating...
currently, i'm using the EC-2 BLACK.
