Yeah, looks real. Although can see why you question, somehow i don't think it is as impressive as it looks, small hands or a good camera angle lending it some size perhaps. I am no expert, but something doesn't look quite right.
Web cam lenses are wide angle. They distort anything that is close to the lense. That's why guys hands look so huge when the reach forward stroking their dicks. It's big but not nearly as huge as it looks.
