to get the stand mount off, use a small jeweler's screwdriver with a hardened tip. radio shack has a set of them.
put the tip between the screw center pin and one side of the hex. the screws are like allen screws except there is a pin in the center to keep out standard allen wrenches.
the screws are anti-tamper like what you may find on your cable tv box, except smaller.
torx bits long enough to fit down to the screw are hard to find
the screw is into soft plastic and is easy to turn once you get a screwdriver inserted.
if you are satisfied with what you bought for the price you paid, what difference would negative feedback make?
