Your right abount the size Mark. When it first arrived I opened the box, and just thought S**t I dont believe how big it is. As Cool-Blew says the web site does not really give an appreciation of scale, but you get used to most things.
I found I had to have several attempts at aligning the swivel connectors, once I got it right have not had any trouble.
The connectors seem quite sturdy, but as yet the instrument has not been subjected to any physical abuse.
A friend of mine says it looks like a TV screen stuck on a manifold.
