*by T***3 on 27 December 2020*

This toy became a favorite this Christmas. Great to be able to crash them and watch them "explode". Easy to put back together again. My only complaint, I suppose, is that you need to pull the cord out pretty fast to get the vehicle to travel well. And even that, it doesn't go too far. But the ones playing didn't really seem to notice. They still had fun. Side note: the locking mechanism is pretty decent and holds up for travel or regular car play.
