We got our 8-year-old daughter a Rover X for Christmas and 4 months later she still rides it everyday.
Now that the weather is warming up she has started riding it outside and has no issues going on our lawn even though she weighs only 60 pounds.
It is expensive but worth it.
Our four kids ages 9-11 absolutely love this board! It runs smoothly and beginner mode has made it very easy for the kids to stay in control. Even works awesome across grass fields. I would definitely recommend the Haloboard!
