Was not easy to find but works great.  We wanted to continue our outside distanced meal times with friends.  We put a double propane heater on one side and this infrared heater on the other side of the table.  We sit at the ends.  It was 48 degrees out and everyone was pretty comfortable.  I should have gotten another when they were available.  I gave it 4 and not 5 because the heat goes forward where it is aiming, not much peripheral heat.
