The station was delivered very quickly and immediately made a good impression. The structure was relatively simple. The terms and length of the screws did not fit always, but that has not damaged the structure. The first exercises were completed smoothly. I am very positively impressed with the station. Why I give only 4 stars ?! I would be delighted if you would review the assembly instructions and would adjust the lengths of the screws. As a final optimization still marked bags of products, since not everyone is a giant space to lay out all the parts has to then before the assembly to check / find.
