Fun, but more importantly, company backed
This was my part of my ten year old son's Christmas gift. He pulled it out and used for less than an hour when one side just quit working. Nothing. I packed it up and messaged the company. They sent out a replacement. We have had absolutely no issues since then. He has great fun running the car around the house, using it under a bowl, pulling a toy wagon, chasing his one year old brother -who is no longer as fearful of it. It's gone down steps and done a bit of running outside, but it does poorly unless the surface is fairly smooth. Battery life isn't super long, but it is adequate for the product. Side note, my son likes to take things with motors apart. Rarely goes back together, sometimes hacked for a bit. Several weeks after Christmas, he started messing with the one not working and turns out there was a wire that had gotten disconnected on the no longer working side, so that's something I would recommend checking if one side suddenly quits as it's working fine now.
