The SMD2489ES, on the other hand, is a ’smart’ evolution, integrating modern connectivity and sensor technology for precise, hands-free cooking.
Both appliances are designed to sit under countertops, offering a streamlined look and maximizing kitchen ergonomics, but the SMD2489ES brings a futuristic dimension with its app-controlled features, automatic sensor cooking, and compatibility with voice assistants like Alexa and Google Assistant.
The Sharp KB6524PSY is a premium under-counter microwave drawer designed with simplicity and efficiency in mind. Its 1.2 cubic feet interior provides ample space for most household cooking needs, accommodating large plates, casserole dishes, or a standard 12-inch pizza. With 1,000 watts of power, it delivers consistent cooking performance across multiple modes, including reheat, defrost, and pre-programmed settings for common meals.
The interface is user-friendly: a responsive touchscreen allows for quick navigation of its 10 preset cooking programs. The drawer’s smooth glide mechanism ensures ergonomic operation, especially in tight spaces where a conventional microwave might be awkward to reach. Though it lacks smart features, the KB6524PSY focuses on straightforward, reliable cooking performance, making it a robust choice for traditional kitchens.

Both models boast 1,000 watts of microwave power, but the SMD2489ES has the edge in precision due to sensor cooking. While the KB6524PSY delivers consistent and reliable heat distribution, the SMD2489ES automatically adjusts cooking times based on the moisture and temperature of the food. This results in fewer undercooked or overcooked meals, particularly when reheating leftovers or cooking delicate items like fish or baked goods.
In practical terms, the KB6524PSY is perfect for routine cooking tasks, while the SMD2489ES offers a smarter, adaptive approach, ideal for busy households or for those who prefer hands-off precision.
Both ovens share a 1.2 cubic foot capacity, making them capable of handling standard family meals. Their identical dimensions (24" W x 16.75" H x 22.5" D) mean they are interchangeable in terms of cabinet fit. Users can expect a similar internal layout, accommodating medium to large dishes comfortably.
The KB6524PSY operates efficiently but without advanced energy-saving features. It runs at full power during operation, and users must manually monitor cooking times to prevent excess energy use.
The SMD2489ES, however, includes smart energy modes that optimize power usage based on food type and weight. Its sensor-driven adjustments ensure minimal waste of energy while maintaining precise cooking, making it a more sustainable choice for energy-conscious households.


The KB6524PSY excels in simplicity, reliability, and solid performance. It is the no-nonsense choice for kitchens where straightforward functionality is paramount.
The SMD2489ES, in contrast, represents a leap forward in smart kitchen technology. Its sensor cooking, Wi-Fi connectivity, and app integration provide a more versatile and efficient cooking experience. It comes at a higher price but delivers a level of convenience and precision that the KB6524PSY cannot match.
The Sharp KB6524PSY offers a larger internal capacity of approximately 24 liters, making it suitable for larger dishes or multiple servings. In contrast, the Sharp SMD2489ES has a slightly smaller capacity of about 23 liters, which is still sufficient for most everyday cooking needs but may be limiting for larger family meals or bulk cooking.
The KB6524PSY provides 1000W of microwave power with multiple pre-set cooking modes, including defrost, reheat, and sensor cooking options. The SMD2489ES also offers 1000W but includes additional smart features like inverter technology for more precise temperature control and evenly cooked meals. Both models support multi-stage cooking, but the SMD2489ES is slightly more versatile due to its advanced control system.
The Sharp SMD2489ES excels in smart functionality. It supports Wi-Fi connectivity and integrates with compatible home automation systems, allowing remote control and recipe updates via a mobile app. The KB6524PSY, while featuring touch controls and sensor cooking, has limited connectivity options and lacks full smart integration, making the SMD2489ES the better choice for tech-focused users.
Both are designed as microwave drawer ovens for under-counter installation, providing a sleek, modern appearance. The KB6524PSY has a more minimalist design with a single handleless drawer front, while the SMD2489ES includes a flush handle design with subtle LED indicators for a more premium aesthetic. Dimensions are similar, but slight variations in panel finish may affect cabinetry integration.
The Sharp SMD2489ES, featuring inverter technology, offers more precise energy control, which can reduce overall energy consumption, especially during low-power cooking or defrosting. The KB6524PSY, while slightly less efficient, has a lower upfront cost. Therefore, if energy efficiency and smart cooking flexibility are priorities, the SMD2489ES may provide better long-term value despite the higher initial price.
