I thought to allude to me after the first. The Naga was a spontaneous purchase. I have not regretted it yet but I'm not quite sure whether it's the right MMO mouse for me. Main reason: weight is not changeable. Does my mouse is too light. Other rodents offer this ingenious feature for a few coal. Well, you can say that I would have previously have known. But it is not so that I could not adjust to me. Still, I prefer for this reason from 1 star. For an MMO like Guild Wars 2, and so the Naga is but one not to be underestimated advantage while playing. I need the keyboard almost exclusively for locomotion, everything else can I control with the mouse. I would probably now opt for a different mouse. The Logitech G600 offers actually the same thing for 10 less and is 20 grams heavier. Anyway, as I said I do not regret the Naga to have bought. By the way of exception not from Amazon but at the "expert" for 80th
