The frame is really stable, the wheels properly, I'll wait how the wheel bearings behaves. The ball bearings are fitted with plastic sleeves on the axle. But: The bag leaves to be desired really left. The seams are not designed to load. If you really purely strangles the 50kg load in the bag, then the bag bursts literally at the seams. Already a strap, one attached to the pocket on the frame with Velcro. I always get my drink bottles (about 6x 1.5l shower) home, because the pocket pants pretty ... Well, the many subjects. The lid is not well resolved, it can not be closed when the bag is full. Definitely a very big relief for the purchase of large quantities family.
