Query: Good idea, poor execution

The smoker works by advancing small wood-chip pucks onto a heating element. But the advancing mechanism gets stuck because the tar or other sticky stuff build up seems to jam to mechanism so you get 20 minutes of smoke. If you want more smoke, you have to go and tend to the smoker and insert another wood puck manually, which defeats the purpose of buying an electric smoker. And the heating element is barely enough to smoke the wood. It has never gotten hot enough cook anything.
