Reasonalble value
This is not exactly military grade but is reasonable for the price.  My biggest problem with it was that it came with a male end and the wire is so light I was afraid to cut it off to adapt it to  use in a breadboard project.  My solution was to buy these female ends: Conwork 10-Pack PCB Mount 3 Pin DC Power Plug Connector Socket 5.5mm x 2.1mm.  They fit perfectly but 90% of my $6.99 (this price way too high) went to waste.  Since the wholesale cost of these female connectors can not be more than about 3 cents each I think one should have been included with this unit.
