One of the reviews gave it 3 stars because it wobbles. Mine does too but it's a minor nuisance. I'm not sure whether the four rubber feet are not flat or my table is not flat. Anyway, it works great. I use it on my nightstand with one burner for the coffee pot and one for my coffee cup. It keeps the coffee plenty hot, in fact the coffee in the coffee cup sometimes gets a little too hot, even for me, especially when it gets less than half full. No problem. I just set the cup down with one side of the cup on the raised edge of the burner and the other side resting on the middle of the burner, so it picks up less heat from the burner. Great for keeping your coffee hot and accessible while watching the morning news in bed. The bottom of the unit does not get nearly hot enough to affect the finish on my wooden chest of drawers. Will also use it for our large parties with a pot of regular and a pot of decaf on this while my BUNN coffeemaker is brewing more.
