I purchased this item to try and reduce the electric bill associated with running the grainfather. On the surface it seems like the process goes fasted and I've noticed that the heating element seems to turn off occasionally now. I did not notice that before. I will say that it's also nice to have wrapped around the machine as it can get hot while you are using it. I will say that while it's easy enough to clean, boil overs mean you need to clean the machine an the coat. Over all it's worth having.
