The scooter is great. It is easy to fold in seconds, absolutely a trip saver. My wife and I could not travel by land, air, and sea without this scooter. Because it has only three wheels to keep the weight down, it is less stable than a four-wheeled scooter. Built-in stabilizer that could deploy automatically would add safety. Our scooter hit an invisible dip & tipped over. A handicapped rider could not prevent tipping over. Otherwise, the scooter is perfect. Good power, good speed & range.
