Just got this one for my 9 year old daughter for Christmas. She loves it! Has a built in bluetooth speaker, which I thought would have poor sound quality. But it actually sounds much better than most bluetooth speakers that people buy. She linked her cellphone to it and has been riding it quite a while while she listens to music. She's ridden it down a gravel driveway with no problems. Very happy with this purchase. Looks and feels very high quality.
