The Blackshark performs as advertised.  The only think that prevented me from giving it 5 stars was the inability to change the date format from Day, Month, Year to the more standard way of reading dates in the USA of Month, Day, Year.  I also was disappointed for the price that the device didn't support receiving automatic time signals to keep the clock accurately set.
