WiFi Mouse: FREE at google play

The first thing I type whenever I search the net is the word FREE. Call me stingy, but I'll take anything that's free. Take the case of this WiFi Mouse. It's free from Google play for a very limited time. Now I don't know what it helps us with. In the first place, I thought a mouse is a rodent that we all want to get rid of. But by the looks of it, I think this will be a very useful tool for those who have laptops and tablets and the likes, and wants to manipulate their screens without the hassle of a traditional mouse. Check it out. I mean, it's FREE.
