Don't refer this product. I have ordered this on August 2012. The sensitivity of this mouse is very less. Please try different product like Iball etc. I request all the customer that don't order this product.

i am using this product from couple of months and it already started giving trouble. it double clicked every time i press left pan and this mouse is so small cant even hold a grip after some time my hands start paining. there is no option to grade less...
