A:Answerhave been using it since we plugged it in about a month ago and it is in our garage and is just starting to get some frost in it hope that helps you. have not had it long enough to really say how often it needs refrosting
A:AnswerIt does have feet, with the front ones being adjustable for leveling.
I just measured mine, 1/16" shy of 56" from the floor to the top of the plastic trim on the door and hinge point.
A:Answerthere is a small gap from the bottom of the item to the floor. Also it is not an auto defrost, so you would have to move it, or have a pan under it when you defrost (likely annually).
A:AnswerDo not put this in a garage. Pamphlet says warranty void if not kept inside house. It says not for garages it is not heavy duty. I am small and can lift it off of the ground by myself.
