My 5 year old daughter got one before she was hardly walking and has ran the wheels off of it almost literally. I think the front end is getting worn out from going over too many ramps and doing too many wheelies. She would hold it in reverse then yank it into second never even lifting her foot, front end two feet off the ground then stop and laugh. Still the original battery and still flies. She just got upgraded to a 50cc four wheeler and wants to give her Tractor to my buddies little boy for Christmas. She grabs some Windex and a Shop towel when we are in the shop and works on cleaning it up for him since she doesn't ride it anymore.
