Used it for Halloween to complement the gorilla costume (which actually came with its own mask but taking one reviewer's suggestion I bought this one separately). And I am glad I did as it is more animated and realistic.  You can move the jaw and the eye slots are constructed so that only eyes are visible.  You may not be able to drink with it on but can be done if you use a straw. Do not smoke thought.  It does get hot in the mask and you don't see as well but that is an acceptable compromise.  Have not found a lot of videos of it before buying it or much info other than what is provided by the company, so if you have any questions on it do ask.
