Bought two for a matching pair with a duo-track slider arrangement.  The wood was very soft and still seemed to have a significant moisture content, so hopefully it will not warp as it continues to dry out.  Lots of rough spots that needed to be sanded out.  Build to build tolerance was pretty significant and I needed a rubber mallet to “tap” some of the vertical panels into place.  One of two kits was missing two interior vertical “end” pieces and had two extra interior pieces, but really didn’t make a difference once they are installed (interior pieces are tongue and groove on both sides while the interior “end” pieces” are not).  Once assembled, the doors were slightly warped, but not noticeably - again, as they continue to dry out, hopefully they won’t get worse.
