Summary: Now days mouse are either jam & slow in response or too sensitive to control sliding on mouse pad. But this is absolutely balanced, firm and controlled in use. Looks attractive. This is my third Lenovo mouse and all three are till date working perfectly.
Summary: Please do not expect a premium feel with this mouse and you cannot shift to this if you have already used expensive mice (I have been using Microsoft Explorer Touch Mouse in my other computer and feel a drop in comfort when I use this). The shape of this mouse is not very palm friendly.
