The aluminum ladder is perfect, super processed and stable. Manufacturers tell me also to the packaging the theme should be improved. The manager came to me in a disassembled cardboard, the edges and plastic parts that were intended as protection and for the optics were partially broken. The manufacturer pointed it, I can see the damage because the manager at me is in use, and I had no time to return at the time. Since everyone must see if return and exchange, but who already buy a ladder on stock required by the artisans so just the same and not to back and forth e-mailing.
