The heating technology in a sandwich maker significantly impacts toasting results. Common options include aluminum or stainless steel plates; aluminum heats fast but may toast unevenly, while stainless steel provides more uniform toasting. Advanced models offer dual-sided heating and adjustable temperature controls. Essential features for buyers include adjustable thermostats, removable plates for easy cleaning, and safety features like auto shut-off and toasting indicators. These elements ensure consistent, customized results.
