We got rid of ours last year when the girls were 7 and 10. They certainly got their use out of it and the PW 4-wheeler over 8 years. But there comes a time when the knees don't fit behind the dash. We have 5 acres, about half is yard, so there was plenty of room and occasion to use them. They have low and high. We started out with low but you will find yourself pushing them over the smallest of hills on low. High is much easier on the parent as they can keep going!
