Double-clicking the left button is a little gadget, take the habit of using it personally for months is not very useful.
Another gadget, the lights on the mouse, it's effect is small, can be fun for a teenager.
The finish is at the level of prices, it in a sense of "cheap", but for the price it is more than correct!
I removed one star because the cable, even if it is of good quality and too short for a mouse.
I recommend this mouse, if you have a limited budget and want to play in the correct conditions. by cons it is a right-handed mouse.
