After having owned a mouse 1st prize unbranded I can only rejoice in this mouse! A good grip, the shape of the mouse fits perfectly in the palm of the hand, ideal for frequent internet or video games. Good accuracy, sensitivity (adjustable) surprised me. The wheel and two buttons (front rear) are new to me. I find it very convenient and I think being able to without. The battery life is more than satisfactory, 2 years of use before changing the batteries. Some may find it too light but I appreciate this feature. I just hope that it is so light does not suggest poor quality. It is plastic and it shows. Do not drop too often
