The CW1 is supposed to be about the same as the CW2.
I expected the CW1 to work as good as any other lnb, and maybe a bit better than dro lbs on skinny transponders. You may be able to return the CW1 if it does not perform well. I am sure that Brian Gohl would say it is defective if it is way down when compared to a dro lnb. He would either say it was defective, or he would say that the CW1 was not installed correctly.
