Query: Is everyone crazy? this thing is great!

The first time I used it worked flawlessly with a 5lb chuck roast cooked 10 hrs nothing burnt it was perfect! now it did overflow a bit but i added a bit too much water which you pretty much dont have to add the meat cooks in its own juices. Also people complained of smoke and smell if you read the book that came with it that is normal for the first couple of uses I highly recommend this one.
