I have never purchased anything from wal mart in my life. They didn't move into socal until 15 or 20 years ago, and by that time I was a union man. Wal-Mart is an extremely anti-union company that works hard to destroy unions around the world.
I think pretty much all cranes have a dip switch setting to control at the very least, the % of time the claw will actually hold a prize. That makes them gambling devices for children in my book. Should all be illegal.
