It is a very basic player; the screen is bright and the player works as normal.  However, Hifiman never cared to put a big battery in it, and the OS is rudimentary to say the most; Hifiman did not support firmware updates.  I would not use it outside in the sun as the screen is impossible to see in bright sunlight.  But, indoors it is amazing.  It sounds brilliant, and is in excellent condition.  This is a collector's item, if nothing else.
