Thank you for allowing me to evaluate your excellent product. In terms of performance it was clearly the best product available on the market. I bench-tested it against a number of other sort utilities and it performed at a minimum of 2.5x the speed of the other programs.
I am therefore in a position to recognise high quality, and your software is amazing.
