Customer Satisfaction & Support
Customer Satisfaction has been a priority for us since the DG8SAQ VNWA was first launched in 2008
We are keen to ensure that our Customers are able to make an informed choice about their VNWA purchase. Download and try out the DG8SAQ VNWA Software first before ordering.
The VNWA software will start up without the VNWA hardware connected. This allows you to check-out the VNWA features and functionality and assess whether a purchase will meet your expectations.
Every effort is made to make the VNWA easy and intuitive to use for new owners, but be prepared to "invest some time" to get familiar with the many uses and options of the VNWA 3 or 3EC. Take a look at the latest version of the 300+ page VNWA PDF helpfile.
