Construction is of vac formed carbon look-alike styrene and seems very well made.
Assembly took a matter of seconds...just two clips to attach with the supplied nuts and bolts, and clip the fully adjustable and nicely padded neck strap on, and the tray is ready to go.
My F-14 tx sits nicely in the tray and seems to be quite secure once pushed in. With the tx aerial extended, the whole tray balances nicely, and the shaped front section fits snugly into my ample girth!
I think it's going to be of great benefit to me, it's very comfortable to wear, so when I get some sailing time I intend to give it a through test.
