External mouse for laptop

In my cyberayya(laptop's pet name), I generally use the touchpad for mouse operations. I got acquainted with it after 3 yeas of using my laptop. For long hours of usage, I thought it is not ergonomic to use just two fingers for mouse operations. It is true. I bought an external USB mouse yesterday. The mouse operations looks easy now with the external mouse connected. I am able to navigate and click faster. Things seems simple, and I like it.
