I unpacked and tested the shopper. It is very stable, the bag is roomy and even has a refrigerated compartment and a reinforcement for the floor. The design of the bag is timeless, so that my mother is there need not to worry at some point in order to be "out". The large wheels are stable and rolls silently away. Because of the large size you can also fine a curb or a step up with it. I am very pleased with my purchase and can only recommend the shopper. The only slight drawback is the high price, but which is justified by the high quality. From me there are 5 star and a strong buy recommendation.
