I upgraded to this mouse from another gaming mouse and i would say that SHARKK is much much better. I have been using this mouse for over two weeks now.
1) Great build quality.
2) Very comfortable to use.
3) You can customize the weight.
4) You can customize the lighting color (this one is my personal favorite)
5) Mouse wire is sheathed and won't tear/rip up easily
1) Position of first side button seems too close for people with bigger thumbs (fat fingers suffer).
2)Scroll wheel LED's color and brightness cannot be adjusted by the software (color of this LED is tied to each profile)
3) DPI button placement is not that good, so knuckle brushes against it constantly.
The mouse has 14 customizable buttons, 8 smartly placed adjustable weights. Wide array of light up color schemes, 5 user profiles stored in the mouse. Comfortable and satisfying scroll wheel. Nicely made ergonomic design, comfortable for those with large and small hands alike. Overall a very good experience in playing games while using this mouse
