yes is very similar. But robuster as the stigma ,never change the run like the amen and its dont loud like the amen. I have try it from a coworker and its runs quieter and smoother. Have not notice any issue with carts like the amen. The cam was always solving by use the amen. And the normal 4.5w motor always needs a push with the fingers to run with carts. All this issue i dont notice with the gold label. For me the better amen -the only bad is you can not change other cams like amen. But its a feature thats nice to have -but its really important? I have only try the other cams and run always with the same .
