The bin system was indeed declared wrong, but still it corresponded to my original order. The numbers were given all wrong. I wanted already do not open the consignment and return it immediately. Fortunately, I have only once opened and taken the consignment inspected. Everything met my expectation, and I unpacked. Except for the pre-drilled mounting holes (the previous bin system) all fit. I only had to drill new holes. Buckets fit.
