I am satisfied with the purchase, I have been using it for more than a year and although there are small jambs, for its price it is superior to analogues (I am talking about razer naga (I have used it for more than 3 years)). Different pros: Lots of keys to configure via software Convenient macro settings Embossed backlit keys Cons: Sometimes mouse profiles are reset, it is treated by importing the finished profile file into the profile folder (before that, you need to delete all profile files manually)
