How do I tell if my Fanatec DD1 FFB is as it should be??

[CRMS]

I've just watched a YouTube video - 1 Year Later... Would I Buy the Fanatec DD1 Again? -

And at 6m 50 seconds onwards it seems that his Apr 2020 DD1 was indeed suspect and needed a factory repair. I got my unit in May 2020 and wonder if my unit is also faulty??

Certainly the video resonates with his comments on ACC and I find the DD1 difficult in that.

I came from a Thrustmaster T150, which was pretty bad, and the DD1 seems OK in comparison. But I have no real comparison.

How do I work out if all is as it should be??
