After getting positive feedback from our latest mouse, the ZOWIE EC eVo CL with its faster scroll wheel and IR LED, we have decided to make changes to our other popular model - the ZOWIE FK. From 2014 onwards, ZOWIE FK will have the 24-step scroll wheel as seen in the EC eVo CL series, which makes scrolling faster. The base will also be having some changes made to it - going from yellow to black. ZOWIE FK will have a built-in IR LED which we introduced with the EC eVo CL Series. If you prefer the 16-step scroll wheel from the current edition of ZOWIE FK you should buy it from our partner stores before it goes out of stock as the next batches of ZOWIE FK will all have the 24-step scroll wheel.
