intuos pro M

My Intuos is very unprecise since I cannot even draw an arrow..
When I'm trying to draw spontaneousely, t's like the pen is led by the top of the edges, my features aren't precises and deviates. Until now I owned a Cintiq 26'' which was much better and I regret its precision. Before my Cintiq I had an Intuos 2, this one was also very good. Should I do some more accurate settings to draw like before or is it only a question of time and habit, maybe a better pen?

Thanks

 

Somebody can reply to me please?
