Query: poor support/broken device

Device failed to amplify the signal and in fact caused some interference. After spending 60 mins with level 1 tech support call was escalated to the level 2 technician who was unable to sort this out either. After 40 mins on line with her I was told that device is clearly defective and should be returned. 1 star rating reflects inability of the tech staff to diagnose and distinguish broken device from operational one as well as fairly poor documentation in as far as what troubleshooting steps and/or options are.
