My expectations were up when described as a robotic. About the same entertainment value as a three dollar wind-up toy. No, correction: a wind-up is probably more entertaining than this. Back and forth it goes, tips over on the rug, legs going cockroach style until is senses that it is upside down and stops. Hey, wait. That's what you can use this dud for - to scare the cockroaches and mice. Twenty bucks wasted. The worse part is that I got one for my eight year old grandson for Christmas. He's going to think I'm really out of touch.
