Hello, this mouse for almost a week. Shipping was fast has lasted just one day. Property me simultaneously ordered a Razer Goliathus Extended SPD. Both were super packed. Thanks to many unboxing videos was unpacking very easy and when you first turn I had not even connect the mouse everything went automatically. The dock has very high quality feet verutscht no mm. Many customer reviews here on Amazon are very old and in time the software has been much improved. Is not perfect but quite remarkable. Found I have more than one profile if you do you have to the oberflaechenerkennung both equalizing else goes the mouse sometimes not at all. An otherwise I would recommend this mouse definitely FRIEND, if that is too expensive but I empfele the Cyborg RAT 7 or the Logitech G502.
