I have all of the name brand mice and this is truly among the best. It is a bit smaller than some of the others like the viper/deathadder/harpe, etc. Love the changeable battery too!

best mouse that i have ever owned and i owned alot superstrike x3, op18k, finalmouse slx and ulx, beast x, x2 crazylight, hyperlight, ko one and so many more this mouse is perfect for my hands

mouse wheel scroll button does not register. everything else on the mouse works very well. updating firmware was a bit complicated. and help center is completely non existent. does not even bother to respond. mouse reads so well on glass pad sp004 buttons feel smooth with a nice tone. no squeaks and does not make mt hand sweat just dont think quality control is good
