Hello guys this is Deepanshu. Today I am going to share my experience with all of you. I had purchased this dell wireless mouse about a year ago. In first 6 months it works good . But after that it doesnt work properly. The range of of the wireless mouse got reduced to work. Many a times when I connect the mouse with my computer it doesnt respond. I had changed its battery but problem is same. Their service is also not so helpful.
