It works pretty well.   Using it to offset the minimal amount of wood chips that can be placed in the Electric Smoker.  The downside is the cheap paint that Masterbuilt uses, it will bubble up and make a mess.  You will end up having to scrap the mess away.  Masterbuilt,  there is a heat resistant paint that you could have used.  Also, the screen on the bottom of the chimney deteriorates rather quickly, the I have not found a replacement for it.  You will have to manufacture something,  when it falls apart.
