The build quality of the metal case is excellent as advertised. Buttons were responsive, but not always. When it worked, not all inputs worked even if the input switch was activated. This was installed in an office that uses 3 printers. DYMO label markers, Brother laser printers and Canon inkjet printers. They were all connected with brand new working cables, so I know that wasn't the cause. In the end I gave them back and went the other way.
