I wasn't sure if they'd use cheap materials to build this but I am pleased and relieved to see it's definitely not.
The housing is thick machined metal, very sturdy as befits a professional product.
The only thing I can find wrong with it so far is the beeping! It beeps every time you go up or down one digit. It's excessive and unnecessary, in quiet environments it would be very disruptive and annoying.
Definitely recommend, despite the high price and incessant beeping.
