The Turbo Defrost feature reduces thawing time by nearly half compared to traditional defrosting, which is particularly useful for last-minute meal preparation.
The venting system is powerful and quiet, capable of handling steam and smoke from stovetop cooking efficiently. Even at higher fan settings, noise remains minimal, enhancing the overall user experience.
