Microsoft Laptop mouse

I like this targus laptop mouse the first days I bought it. But, as months passed by, it became slower and slower. Every time I will use it, I need to bang it on my table as if I was angry on something. With my wife hearing it all the time, she forced me to buy another brand. And right now, I am using Microsoft laptop mouse and I’m comfortable with it! In this new one, there is no need for me to bang it on the table as it is functioning well!
