We bought one for our 10 year old for Christmas. Daddy charged it up the reccomended time and we wrapped an empty box for under the tree. Christmas day, it would die as soon as unplugged, no matter what we tried. Emailed Amazon and they sent a replacement immediately and refunded once the original was dropped off at a UPS office to be returned. Second one arrived right away and charged right up. It has lights and connects to Bluetooth so the kids love riding it while playing their favorite songs. We live on a dairy farm and it goes on the gravel driveway, paved barn floors and across yards and pastures. We will be buying two more for the younger siblings.
