Pros: this product does not live up to it's pricing...faulty jump issues and reall bad service
Cons: "Your RMA request for exchange or refund has been forwarded to the processing department." thats what the email said from tech support...they say it's automated with an attached name and i won't get a refund
Summary: Mouse has good precision but bad ergonomics - great precision - great looks especially multi color LCD's - Extremly poor ergonomics I rate this a 5 on all aspects except the ergonomics. You simply cant find a good way to hold this mouse. Sides are too small and you keep hitting the buttons by the thumb. The mouse buttons grooved and slippery due to the coating used. There is also no weight changing system as what you would expect in a mouse of this caliber.
