The support was delivered quite fast with me and would probably soon been assembled, if not 2 plastic parts have been delivered incorrectly would allow you secured the support tube. At the point of praise to the supplier who has obtained replacement within 2 days. The service was so flawlessly. For carriers are to say it he is very stable and still relatively easy is to be handled. I mount it again and without needing help. Only the holding arms give me food for thought.
