Even pavement edges of 3cm height make for this model is a serious problem because not enough "leverage" is to tilt the car at the edge available. The push handle sits almost vertically above the rear axle. Downstairs - a disaster, you get stuck with the parking brake on the steps. The foam rubber wheels after one week, added intensive use, already full of holes, the footrest rattles when driving and the rubber on the handlebar turns freely which control the once difficult.
Conclusion: The design was apparently never seriously tested, the workmanship is poor and therefore the usefulness insufficient.
