I bought this to use as an aid to get me through college. I was very excited! When I received the skeleton it was almost assembled. All I had to do was add the legs, adjust the head, and connect the pole to the stand. I noticed that one arm is gathered back, preventing it from moving properly. I also noticed that when I connected my legs to the thigh, they rubbed so much that I couldn't move my leg forwards or backwards. It was a disappointment for the money I spent on it. I tried to figure out how to fix the arm and both legs but to no avail so I left it alone. I really like how it comes with a book and study guide, as well as the cute pen that comes with it. Overall it will still serve its purpose, but my concern is that the legs will rub against the thigh area.
