Checked out the other reviews. As instructions state, don't overfill and you'll be fine be fine with the oil storage.Entire assembly comes apart pretty easy for cleaning.Received mine with a small dent in the side but was not work the hassle to send back. Used it 3-4 times so far and works great. The cover helps keep oil from splashing but does store some condensation that drips into oil. Oil storage is a great idea.Cons:Storage Container design should take into consideration for some extra oil.This would help with most negative reviews and oil spills.
