I reviewed a lot of reviews, visited several stores, chose a gaming mouse for myself. The choice eventually came down to 1)Cyborg R. A.T 9 2) Razer Naga Epic 3) and to this mouse The first option was dropped. too futuristic mouse and not enough keys 2) the raiser was disappointed by the reviews about the quality of the mouse itself and It was decided to take the Logitech G600. The rodent cost 2700. While the term of use is 1 day, but it is already clear that the purchase is wonderful, in fact, all the disadvantages described are the result of getting used to another mouse and over time they will come to naught. Verdict-who wants a gaming mouse with many keys, I advise you to take this rodent.
