The quality of the machine is very good, professional quality. I was disappointed in the amount of time this took , it was delayed one month because of a European month holiday. However quality of the Digital Printing is excellent, exactly what was provided to them. Some of the chassis don't have aluminum back plate, so I redesign mine in 3/16 aluminum and was cut on a water jet locally. So I happy with the results but be aware some chassis are sheet metal on the back making it complex to machine and drill when you have XLR connectors.
