On my personal experience this is very wonderful wireless mouse in this price range. And you all know that brand name of it , the Lenovo . This mouse is really very user friendly and so reliable and with easy to handle and one more thing is that it is lite weighted also.The specification of this mouse is that it comes optical feature which mean it does not use laser light to move mouse curser which is the good feature of this mouse. You can use remote cell as it power source. The wireless range of the mouse is 5 to 10 meters. And service and support of the company is very nice and good according to the brand name of it. So I hope you like my review on the Lenovo N50 Wireless Mouse.
