Extremely basic, say it's a gamer mouse makes a little smile. It has a so-called Gaming mode, but it means that the side buttons control the volume +/- and front black button is used to fire button, that's all, it's a can just to qualify gaming mouse. You press the top button to change modes simply, but there is no visual feedback so you never know which mode you are. The other mode is the Office mode and there, the side buttons are used as forward / reverse in the pages and front button is used to hide or open windows Windows and that's it too. Note also the additional possibility of adjusting the speed of movement (useful for games or applications). The mouse is simply delivered in a small carton low end and no driver or CD (all done manually with buttons), delivered still with the USB dongle and battery. On the plus side: it is quite comfortable, with a nice size not too big, not too small, glide well, feels good in the palm of the hand and sufficiently heavy. It turns off automatically when the PC is turned off. It works immediately and is recognized perfectly under Windows 8.1, the wireless connection is flawless without interruption. In short: mice low cost, do not expect miracle that price, to use as a conventional mouse and expect nothing for the gaming. Its pleasant comfort level catches up a bit. I bought it as an extra mouse and as such I am not disappointed.
