I use this item primarily for long heated rest for smoked beef brisket. This warming oven is plenty large, and construction quality seems acceptable (not incredible, but appears fine). I checked the oven's temperature calibration with a separate thermometer, and the oven temperature is correct. It also comes with a small water container at the bottom of the oven to provide some extra humidity, which is helpful to prevent meats from getting dried out during a long heated rest. As the other reviewers have stated, removing the protective plastic from the oven out of the box is a huge pain in the butt - plan for that to take a couple of hours or more, depending on how picky you are. But functionally it's working great for me.
