Are you kidding me? Rated 1 out of 5 stars

Awful.
I would give zero stars if I could. It's about the most annoying add-on I've ever tried out. After one test search I was more than done with it.
I guess some people now have a 1/2 second attention span and can't stand it when they use a keyboard and flashy things don't appear on screen.

But - hey - don't take my word for. Try it online!
