Does not even preform to minimum standards. I have burn on the back of my hand to prove it! Was getting something off the bottom rack, and I hit the back of my hand on the top guard. Imagine if I was doing what YOUR picture shows! Why does the picture show someone pulling the rack out with your 'warm to the touch' guards!! Warm to the touch!! They would have severely burned their fingers! Worthless product and deceptive advertising. Waste of money! Have requested refund.
