MR-2020, MR-2017 specifications

The Toshiba MR-2017 and MR-2020 are innovative microwave ovens that exemplify Toshiba's commitment to advanced cooking technology and user-friendly design. Designed for modern kitchens, these models combine efficiency and versatility, making them ideal for a wide range of cooking tasks.

The MR-2017 features a compact design perfect for small spaces without compromising on power and functionality. It typically boasts a 700-watt microwave output, providing sufficient energy for heating and cooking various dishes. One of its standout features is the one-touch cooking options, which allow users to select heating times and power levels with a simple press of a button. This functionality is particularly advantageous for busy individuals looking to save time in meal preparation.

On the other hand, the MR-2020 offers enhanced capabilities with a slightly larger capacity and a higher wattage output of 800 watts. This model not only heats food but also includes grill and convection settings, allowing for more versatile cooking methods. With the grilling function, users can achieve crispy textures similar to conventional ovens, while convection cooking promotes even heat distribution for consistent results.

Both models are equipped with advanced technology such as the smart sensor cooking feature. This technology automatically calculates the optimal cooking time based on the food type and quantity, ensuring perfectly cooked meals without any guesswork. Safety is also a priority, with child safety locks that prevent accidental operation, making them suitable for families.

The control panel on both the MR-2017 and MR-2020 is designed for ease of use, featuring intuitive buttons and a clear display, making it accessible for all users. Additional features include defrost settings for quick thawing and various pre-set cooking modes tailored for specific food types like popcorn, pizza, and baked potatoes.

In conclusion, the Toshiba MR-2017 and MR-2020 microwave ovens blend advanced cooking technologies with user-friendly features, catering to diverse culinary needs. Their combination of power, safety, and convenience makes them a valuable addition to any kitchen, ensuring that delicious meals are just minutes away. Whether you're reheating leftovers or trying out new recipes, these models are built to deliver performance and satisfaction.
