HORRIBLE! my husband was putting together the car and noticed these two large cracks on it. by that time it's 2 days away from Christmas and that it's too late to replace it. 
Today my 5 year old son rode it for the very first time and less than an hour of using it one of the tires came off while he was driving it and almost fell off the car!!! good thing he was driving it slow otherwise he would have flipped. Will contact Customer Service and will ask for a replacement!!! What a disappointment Wayfair that the quality is so cheap!!!
