Only the gray mouse works in reverse, from time to time it goes forward, the black mouse only goes forward and only from time to time backwards. I was hoping to get a fun little cat toy and something to scare the kids with.
Pros
Battery operated: Simulated wireless remote control toy powered by 3 x 1.5V AAA batteries (batteries not included), controller powered by 2 x 1.5V AA batteries (batteries not included)
