The Upromax Induction Plate and Converter Disk is a versatile heat diffuser designed to improve cooking on induction and other stovetops. Made with a three-layer construction of stainless steel and aluminum, it spreads heat evenly, helping prevent hot spots that can burn sensitive foods like caramel, rice, or sauces. Its 9.5-inch size fits most pots and pans, and its slim 0.5-inch thickness allows for efficient heat transfer without adding bulk.

It is especially useful if you want to use your existing pans on induction stoves without buying expensive new cookware. On the downside, some users may find it a bit heavy at 1.76 pounds, and its performance depends on proper use with the right pan size. Also, while it is good for low to medium heat cooking, it might not be ideal for high-heat searing.
