Extron SW8 HD 4K HDMI Switcher.  All HDMI ports have been tested and work.  There may be small scuffs or scratches, but otherwise superb condition.  Power cable is included.  The unit is found and can be configured with Extron's PCS software.  This unit is the last of a lot of 10 units.  This unit has a very sensitive channel 2 button, so it is recommended not to use that channel.
