I what this mouse for my laptop a few months ago. In the beginning the mouse worked absolutely fine , but after a few weeks of usage it sometimes failed to respond. While using the left click of the mouse sometimes freezed and sometimes the right click. The scroller of the mouse also did not give a good result. I informed zebronics customer care service about this issue but they can't explain me about it and said that it might resolve after sometime. But its not working till now. Very bad product. And least responsible customer care support
