Query: Totally Disappointed

I bought 2 of these for my nephews and we returned them the next day. They work on infra red controls which are so unreliable that even the slightest hand movement can interrupt the line of sight control signal. Even when the signal was working it occasionally interfered with the other robot. We were very frustrated. R/C toys are so much better. These are way more frustration than fun.
