Out of the box the plastic feels flimsy, not much better than a plastic Chinese take-out tray. The lid had to be pushed into shape to meet the base. The heating mat is either on or off, with no thermostatic setting. You’ll need to use your own thermometer and adjust the lid vents as needed. The led light fixture is fine in itself, but it just sits on the lid without being secured in any way. You’ll need to provide your own timer for the light. Very unimpressive, especially at this price point.
