Tried for an hour to make them fight.. gave up.. It seems like the infra red doesnt register all the time..Kinda a let down - maybe ill try again.. sighThese robots are pretty lame. They make alot of noise but are very hard to maneuver and controlI bought this battle zone fighting robots for my nephew who really likes to play with robotic toys for Christmas I'm sure he'll be happy to receive it.Kids love itWe bought these robots in lieu of the Rock em Sock em and have been very pleased. My boys (6 & 8) have had many hours playing with the robots. The only down side is that they do drain batteries pretty quickly.My mom had purchased this for my son and it was his big present this year. The demo mode ran fine, the training mode was pretty hit or miss and the battle mode was impossible. The robots rarely responded to the controller, honestly infrared is a poor choice for something like this, radio frequency would have been much better. I wish I would've read other reviews for this before my mother bought it. It broke my heart to see his excitement turn to disappointment. We're getting Rock'em Sock'em's instead.
