If you are struggling to use the Medicus driver, its sensitivity can be adjusted, affecting the ease with which the hinges will break down. This means you can alter the amount of precision you require to make a successful swing as you progress. The club can be used either just to make practice swings, or to actually hit real golf balls.
You may find the club a little awkward to swing at first. It is heavier than a standard club, so will feel very different. Persevere and you will find that only a few minutes use of the Medicus driver will mean that swinging your usual clubs feels light and easy. You may find it tricky to hit balls with the Medicus without tightening the hinges, so allow for this if you do want to use the club this way.
