Here you can see the difference of a little more expensive items compared to cheap products once again. And really clear. The wheels smooth and quiet running. You can hear the car while running virtually non. The frame makes a stable and secure impression. Nothing is loose. The bag stable, large and very importantly, easy to remove. The material is strong and stable. And you can wear the bag as a bag the handles are long enough. I am extremely pleased with the shopper and can only recommend it. One should not be deterred by the price itself. That he is worth.
