I purchased a stainless steel set after reading the about the dangers of aluminum. I purchased this set because of the good reviews, the video and the great price. The description  and photos are accurate. Retain heat well. Heat up quickly. I have a gas cooktop.  In order to avoid burning, must keep the heat on low or medium and pay close attention. Food sticks to the bottom. Soaking in warm soapy water for a few hours does the trick. The small sauce pan had rainbow stains after making beans with oil, vinegar and a bunch of spices. I used barkeepers friend to remove the stains. The shine returned leaving them like new.
