Query: interactive amazing dinosaurs

I am a preschool director and am very familiar with Constructive Playthings as a wonderful source of educational products. I ordered for Christmas the Interactive Amazing Dinosaurs for my 4 year old grandson who is very interested in learning about dinosaurs. He played with it once then it stopped working. His parents replaced the batteries but it still did not work. I contacted Constructive Playthings and they immediately sent a replacement. We opened the package, turned it on, it made one sound, some lights blinked then it stopped. A reset button on the back said "If unit stops from operating press reset button once". We pressed it, the toy said one sentence then quit working again. We did this several times but this toy just does not work. There is a light that does not go off. I now have two toys to return and a very disappointed grandson. Do you think that this toy has a problem????
