Buying Guide
FAQs
How do I choose the right capacity for my kitchen needs?
Look for a microwave that offers at least 1.4 cu ft (≈40 L) if you frequently cook family-sized meals or large dishes like pizzas and whole chickens. Models such as the Toshiba ML‑EM45P (1.6 cu ft) and GE 2.0 cu ft provide extra interior space, while compact options like the GE 1.0 cu ft are better for small apartments. Consider the turntable diameter as well; a 13.6‑inch turntable can accommodate larger plates compared to a 12.4‑inch one.
What are the benefits of inverter technology versus traditional microwaves?
Inverter technology delivers continuous, variable power, which results in more even heating and better texture, especially for delicate foods. The Toshiba ML‑EM45PIT model highlights this feature, offering faster cooking and reduced hot spots. Traditional magnetron‑only microwaves may be cheaper but often overcook the edges while leaving the center underdone.
Should I prioritize a microwave with smart sensor menus or manual power levels?
Smart sensor menus automatically adjust time and power based on food moisture, making them convenient for everyday items like pizza, potatoes, and vegetables. Models from Toshiba and GE include 6‑10 preset sensor menus that simplify cooking. Manual power levels give you more control for specialty recipes, so choose based on how much you value convenience versus flexibility.
Is an air‑fry or convection function worth the extra cost?
An 8‑in‑1 combo like the Toshiba Air Fryer Microwave adds air‑fry, bake, broil, and convection modes, letting you replace a separate oven or fryer for healthier meals. While the price is higher, you gain versatility and can achieve crisp results with less oil. If you rarely use these functions, a standard microwave with high wattage may provide better value.
How important is turntable size and position‑memory for cooking larger dishes?
A larger turntable (13.6 inches) accommodates full‑size pizzas and casserole dishes, reducing the need to remove food for even cooking. Position‑memory turntables, found on several Toshiba models, return the plate to its original spot after each cycle, improving safety and consistency. If you often cook big items, prioritize these features.
What should I look for in safety features like child locks?
Two‑step child locks prevent accidental operation and are standard on most Toshiba, GE, and Black+Decker models. They typically require a specific sequence to unlock, adding an extra layer of protection for households with children. Ensure the lock can be easily deactivated when not needed for convenience.
How do I assess overall value when comparing price, power, and features?
Balance the microwave’s wattage (1000‑1250 W) with its capacity and extra functions; higher wattage shortens cooking time, while added features like sensor cooking or air‑fry increase versatility. Models such as the Toshiba ML‑EM45PIT (1250 W, inverter, sensor) offer premium performance at a mid‑range price, whereas the Farberware 1000 W unit provides solid basics at a lower cost. Evaluate how often you’ll use each feature to determine the best cost‑to‑benefit ratio.
