?Took approximately 2 1/2 hours to put together.Upon taking it out of the box yesterday, my 2 1/2 year old son was super excited. And was very eager to play with it.We got it all put together and let me tell you HE LOVES IT!!! Goes fairly fast, drives great, easy to maneuver. Love that it goes forward and reverse and it also has 2 speeds (low and high). Have not had any problems with it as of yet. The remote control is amazing and awesome for parents to control where it drives. It does take 7 AA Batteries. Has 4 working lights. The radio is awesome and fairly loud. Comes pre loaded with a handful of songs but also has an AUX cord so you can plug an ipod or whatever into it. All and all for the price I believe it is a great buy.
