The scooter is processed massive and quite wertig, I was surprised given the price. Also holds comfortably 90kg without having to fear the footboard could break. Good adjustability and the removable handles make transport easy. The tires are solid rubber and have a very smooth surface, the brake is painted metal which is pressed onto the tire. That this is not an ideal combination, is obvious. Works in children though (for the scooter has also been acquired), but an adult brakes so difficult because simply the friction is not big enough. The tires may leave marks on parquet / laminate, but quite simply can wipe again with wild game streak.
The next time you purchase I would probably pay attention to soft rubber tires or a brake with a kind of brake pad. Older children (perhaps as from primary school age) I would not let on that ride scooters.
