Customer Reviews
Customer Review: “I bought this microwave primarily because, after 75 years of commercial availability, the intelligence level of our society has collapsed to the point that it intersects with the mad rush to have the government regulate everything… Even when it’s for the children! I have no doubt this microwave is actually using all 700 watts of its rated power.”

Frequently Asked Questions
Q: What does the “Add 30 Seconds” feature do?
A: The Add 30 Seconds button instantly adds 30 seconds to the current cooking timer without resetting the cycle. This is useful when you realize your food needs extra time mid-heat, eliminating the need to re-enter the full duration.
Q: Are all 0.5 cu ft microwaves suitable for small kitchens?
A: Yes, these compact microwaves are designed specifically for limited counter space. However, always measure your available area before purchasing, as external dimensions vary slightly between brands.
Q: Can I disable the child safety lock permanently?
A: Most modern microwaves—including those reviewed here—allow you to turn off the child lock via a specific button combination (often involving holding multiple keys). Refer to your owner’s manual for exact steps.
Q: How many watts should a compact microwave have?
A: For best performance in a 0.5 cu ft model, aim for at least 900W. While 700W works for light reheating, higher wattage ensures quicker, more even cooking—especially for frozen meals or larger portions.
Q: Is it worth paying more for sensor cooking?
A: If you frequently cook varied foods or struggle with timing, sensor technology (found in models like the TOSHIBA EM131A5C or LG NeoChef) can prevent overcooking. Otherwise, simpler models with preset buttons offer excellent value.
Finding the perfect 0.5 cu ft countertop microwave with Add 30 Seconds doesn’t require sacrificing performance or style.
