The install is one of the easiest things you can do, and it takes no time at all

The fortunate thing is that the errors tend to be consistent, so once I'm used to the errors in that session, I can do things like look just below where I want to click and it usually works

I love this thing, at first it took some time to get used too but playing games just got more easier and more convenient

This thing is completely useless unless you have some sort of disability that prohibits use of normal mouse inputs, if you are disabled in such a way you're probably used to being frustrated by things not working as you would like and in that case this might be for you.
