I've always felt the Mercedes fan on low, was too low. It needed to be about 15% more blowing effort to prevent me from having to switch to a higher fan speed.

Well I guess I got my wish. This Chinese (I'm assuming it's from China anyways) regulator is set just that 10-15% higher blower speed than my 2 previous regulators. The drawback now is that I can hear the fan blowing on low. Prior to that, I wouldn't hear it when on low.

Oh well. At least it's working properly.
