I placed many many phones inside of the robots mouth. And if it thought they were tasty enough it would offer from $3 dollars up to $7 dollars for its cellular snack. The robot is placed at Walmart supercenter in between the entrance doors. for maximum exposure to all customers . While I fed the robot phones it educated me about the hygiene statistics of people in japan. At one point the mechanical horse thats located two feet away was activated by a mother and her 3 year old child so I had my ass pummeled Everytime the mechanical horse lunged forward all while listening to oh Susanna play from the mechahorse. I did get 33 dollars for my 13 smart phones so I give this 3 stars and recommend it at least for the horse experience go ecoatm.
