I think Tekno the Electronic Robot Puppy is well worth buying. I have a Poo-Chi and Tekno is more fun to play with. Tekno walks ,shows emotion, and BEST of all has an on/off switch! Poo-Chi is cute, but my son and I soon lost interest in playing with it. We never get bored playing with Tekno. He is the closest thing to a real Puppy!
