With just 8 x AAA-size batteries, the MINI-Z Racer allows anyone to enjoy the beautiful style and advanced performance of R/C cars.

I received a broken one. The model wasn’t secured to box with straps, so it was spoiled while shipping. One of the front parking lights fell off and, of course, is lost. Now the car body is defective and I’m really disappointed.

This thing is super fun! My dog chases it all over the living room and it’s a good time. Very powerful- although at first I was disappointed and looking into new motors because it ships in training mode and I didn’t find that out until I read the instructions. Plenty of power now and the steering and throttle control are very sensitive and fun to operate. Very happy with this purchase and need to save up for another for some side by side racing action.
