Query: Cute concept but...........

Koby the bear is a good concept if you can get it to work properly. I bought this for my son last Christmas. At the time he was 5. His little heart was broken when he tried to talk to it and it would not respond properly. I exchanged it for another Koby, and it had the same problem! The only way we were able to get him to respond properly was to have no background noise, and to speak into his microphone around his collar. But even then it worked 50% if the time save your money... it's not worth buying. Unless, you just want him for his cuteness.
