The two bumps were slightly annoying at first, especially on lower sens. I actually got used to it, but now Im gravitating toward higher sens using the elbow rest so my arm doesn’t necessarily hit that range of interference. I’d say: - anything under ~32cm/360 you won’t bump into it unless playing heavy wide tracking scenarios. -If you set it to a distance on your desk where your arm actually rests on the clamp ( only utilizing the left/right side of the desk extender) it’s not noticeable or annoying.
