When I follow “Mixing Shader Components” lesson the result looks quite different from what is seen in the video. There is a lot of noise and the color is very splotchy on the object. This is the screenshot: https://www.dropbox.com/s/nikophhk9jti8ml/RenderNoise.PNG?dl=0
Am I doing something wrong?

It looks like very low roughness value for the Glossy BSDF causes the issue. If I increase it to 0.05 it pretty much removes the speckles and makes the picture look much more natural.

Interesting solution. Up till now I didn’t know the glossy roughness could have such an effect on fireflies. I would have guessed multiple importance sampling for lights..thanks for following up on your comment!
