Was fun building it for my kid and when it works, it works okay.Somethings you should expectthe gears are plastic, so any resistance will cause them to wear fast.The wires are extremely thin, you should solder them on. If you don't you may find the kits may not work well or at all due to not enough power.The wood needs to be handled without too much pressure or it will break.Don't make things too tight or it will cause premature wear or cause the car not to move.
