A mouse with a lot of ambiguity. At this price, you might want to consider another brand, such as Zowie, which is utilized by a significant number of professional gamers. If you are an avid gamer, you should consider this option. Many advantages: Lighting that is both beautiful and designed It's easy to use after you get used to the shape of the mouse, but it takes some getting used to after using another brand. Plenty of additional control buttons Inserts made of rubber on the side The scroll wheel on this mouse is easily the nicest I've ever used. Superb braided wire that can be bent easily on the top sensor. A year of use has not diminished its effectiveness in any way. Having these drawbacks: Very pricey in each of our locations, 6000r The software is completely poorly planned, and the translation is erroneous, just like a4tech and Bloody. Due to the lack of a comprehensive warranty, if you bought it outside of the United States, then in the event of a malfunction, the official (global) support of Razer will direct you to the reseller from whom you purchased the mouse in the first place, and they will ask you to send the mouse back to them in their original countryโin my case, Germanyโat your own cost. If you can produce proof that your mouse has broken down as well as receipts, Logitech will gladly send you a replacement mouse at no cost.
