A good copy without jambs got me the third time. There was one return and one exchange. The first had a terrible click on the right button, the second had a mowing wheel, on which, in the cut-off mode, these cut-offs were barely felt. A large percentage of marriage is the problem of the raiser. I got hooked on Razer after I was given Viper Ultimate as a gift. A super fast mouse that doesn't seem to be in your hand. She is so light. In addition, she is too short and thin for my hand. Once in the store I touched the g502 Hero from the Logic and realized that here it is perfectly in the hand. But mechanical buttons do not inspire confidence. Monitored Razer, and it turned out that Basilisk is Hero, but with much cooler stuffing. At first I took Basilisk Ultimate, but there are too many controversial decisions in it - I returned it. Then I took the V3 - a buzz) I hung the wire on the bungee, also from Razer - conveniently.
