I bought this recently and it does not work.  I am more than a bit of a diy kind of guy.  Usually able to work around minor problems that happen in projects.  But the male electronic plug would not snap into the female.  Should not be a problem as it is clearly labeled "UP."  Did not have side "guiding" extrusions that would insure proper alignment, but then again there is only one way to align it.  The prongs appear straight.  So apparent reason that it would not just snap in.
