Lots of nice features.  180 degree ratchet will allow the tablet to slant up or downwards.  Expandable cradle will fit tablet widths from 4.5 to 7.75 inches and heights from 5.5 to 11 inches wide (that covers most of the tablet universe).  Works in portrait and landscape modes with a nice swivel feature.  Attaches easily to the driver or passenger headrest posts.  Cases and skins are not a problem with this mount.
