I work mostly with MDF

The media could not be loaded.  To start off you can pull a joint together with this it's just not the best device I've seen.The leveling screws need to be used independently i.e. adjust the screw opposite of the side you need to raise, the suction cups grip well on a clean surface but keep in mind that the leveling screws are prying against it.You also need to adjust the leveling screws before using the draw screw to bring the joint together as the draw screw pulls against the leveling screws making them hard to turn.Overall it works but there's a huge amount of play in all the attachment points which hurts any precision you might achieve.
