I have experienced the staff at DTI as very skilled and punctual. At the same time, I have received good service and flexibility as I was allowed to follow the test and build the enclosures around the insets.

I would definitely recommend other Nordic importers to have tests performed at the Danish Technological Institute, says Tony Eide, CEO, Norvai.
