The quality of both the mouse and the wire is very good. I bought it for 299/-. At that price it is the best. I also bought another mouse for same price which is "HP x1000". But that HP mouse is very small in size. Please note that point, because that HP mouse is no 1 seller in mouse. It is suitable for children and adults who have Small hands. But the "Logitech M90" is not like that, it is the perfect size for both left and right handed people.
