Reliable everyday performer with quiet operation and sensor cooking that handles most household tasks effectively.

Check on Amazon →Opens at amazon.com · affiliate link

Ideal for: Apartment dwellers and small households who value quiet operation and straightforward controls.

The Toshiba hits a sweet spot for most households. It delivers even heating, quiet operation (a feature several owners specifically praise), and sensor technology that adjusts cooking time based on food moisture, which eliminates a lot of guesswork. The mute function is genuinely useful if kitchen noise bothers you. The 1.2 cubic foot capacity is modest but adequate for standard plates and containers.

That said, durability is a real question mark. Some owners report the unit failing within a year, though others have kept theirs running for years with no issues. The replacement experience, when warranty claims do happen, can be slow and frustrating. One buyer waited two months for resolution. The interior also isn't seamless, so food particles can get trapped in crevices, which means cleaning takes extra care. Compare this to the GE's larger capacity if your household heats multiple large items regularly.

For daily reheating, defrosting, and basic cooking, this Toshiba punches above its price point. Just go in knowing that longevity isn't guaranteed, and you may need to be persistent if anything goes wrong.

Pros

  • Quiet operation sets it apart from many competitors
  • Sensor cooking adjusts power based on food moisture
  • Mute function eliminates unwanted beeping entirely

Cons

  • Mixed long-term durability reports spanning 1 to 10 years
  • Interior has seams where food particles can lodge
Key features
  • 1.2 cu. ft. capacity with 1000-watt output
  • Smart humidity sensor automatically adjusts cooking time
  • 10 power levels with easy defrost by weight or time
  • Mute function and ECO mode for energy savings

Spacious 1.6 cubic foot capacity with solid sensor cooking, ideal for families who need room for oversized dishes.

Check on Amazon →Opens at amazon.com · affiliate link

Ideal for: Families and households that heat large items or multiple dishes simultaneously.

The GE steps up to 1.6 cubic feet (a meaningful jump from the Toshiba) and that extra interior space matters if your household regularly heats multiple plates at once or tackles larger containers. Owners consistently report even heating and strong popcorn performance with minimal kernels left behind. The build feels competent, the controls are straightforward, and it runs quietly, making it an easy daily tool to live with.

The trade-off is complexity and ease of use. Several buyers noted that the control panel feels cluttered and less intuitive than older, simpler microwave layouts. The buttons and lettering aren't illuminated, so reading the panel in dim light requires closer attention. One early reviewer reported a sparking issue within weeks of purchase, though most units appear to operate without incident. Where the Toshiba leans toward simplicity, this GE emphasizes capacity and features, which appeals to larger households but may overwhelm someone who just wants to punch in a time.

If you're replacing a similar-sized unit or have space to accommodate it, the extra volume and even heating make this a solid step up from compact models. For those shopping kitchen appliances broadly, this GE complements other countertop tools well: much like how a ceramic air fryer suits a kitchen where you want specialized cooking options alongside your microwave.

Pros

  • Spacious 1.6 cu. ft. interior fits full-size dinner plates
  • Even heating and excellent popcorn performance
  • Child lock is easy to disable when not needed

Cons

  • Control panel is complex with non-illuminated buttons
  • Some early units reported sparking or electrical issues
Key features
  • 1.6 cu. ft. capacity with 1150-watt cooking power
  • Sensor cooking automatically monitors moisture
  • 8 convenience cook settings for everyday foods
  • Manual and auto defrost with weight or time entry

4.2(22,523)

Affordable compact microwave with solid basic performance, though durability and noise concerns emerge after extended use.

Check on Amazon →Opens at amazon.com · affiliate link

Ideal for: Budget-conscious buyers willing to accept durability trade-offs for lower upfront cost.

The Black+Decker at 1.1 cubic feet delivers the essentials at an entry-level investment. When it works, owners find it heats reasonably well and operates without drama for everyday tasks. The push-button door is convenient, and the compact footprint fits tight spaces. For someone on a tight budget or needing a backup unit, the low barrier to entry is appealing.

The durability picture is troubling. Several owners report the fan failing within weeks or months, leading to steam and water accumulation inside the unit. The warranty process is notoriously frustrating; one buyer spent weeks navigating phone trees and email chains, only to be told the model wasn't covered, despite buying it through Amazon. Noise is also a legitimate complaint: owners describe it as significantly louder than typical microwaves, with a heavy buzzing rather than a hum. The unit also slides across smooth countertops without anti-slip feet, creating a genuine safety hazard. Compared to the Black+Decker's smaller 0.9 cu. ft. sibling, this 1.1 cu. ft. model doesn't offset the reliability concerns with enough capacity advantage to justify the risk.

If budget is the only factor, this works short-term. But the warranty experience and early failure rates suggest spending a bit more on the Toshiba or smaller Black+Decker is a safer bet.

Pros

  • Low entry price for basic microwave functionality
  • Push-button door release is convenient
  • Compact 1.1 cu. ft. size fits modest kitchens

Cons

  • Venting fan failures and steam buildup reported within weeks
  • Warranty claims process is convoluted and frustrating
Key features
  • 1.1 cu. ft. capacity with 1000-watt output
  • 10 power settings and 30-second express cooking
  • Pre-programmed buttons for 6 common foods
  • Child safety lock with push-button door design

Powerful 2.0 cubic foot capacity with 1200 watts handles large items quickly and quietly, excellent for busy households.

Check on Amazon →Opens at amazon.com · affiliate link

Ideal for: Larger families and busy cooks who value speed, capacity, and reliable, even heating.

This GE brings the biggest internal space and highest wattage of the lineup: 2.0 cubic feet and 1200 watts: which translates to genuinely faster cooking and room for oversized platters, large bowls, or even small turkeys if you're feeling adventurous. Owners rave about the quiet operation, the intuitive keypad, and the fact that it heats food in noticeably less time than older 900-1000 watt models. One buyer mentioned their previous microwave took two minutes for a task that now completes in 45 seconds. The interior coating is durable (one reviewer praised it for outlasting the flimsy painted surfaces on other brands), and the overall build feels solid.

The main quirk is the mandatory child lock and learning curve to disable it, though GE provides clear instructions and most owners find it straightforward. The heating performance is rock-solid and consistent across a variety of foods. Where the smaller models sometimes struggle with even cooking or require you to rotate items manually, this one's power and size eliminate most of that friction. If you're stepping up from a compact model, this represents a meaningful upgrade in daily usability. Compared to the Toshiba's more modest footprint and output, you're investing in both capacity and speed.

For households that cook or reheat multiple items daily or regularly deal with larger portions, the performance bump justifies the step up.

Pros

  • 2.0 cu. ft. capacity and 1200 watts for fast, powerful cooking
  • Very quiet operation compared to competitor models
  • Durable interior coating resists peeling and wear

Cons

  • Child lock is mandatory though simple to disable
  • Larger footprint requires adequate counter or shelf space
Key features
  • 2.0 cu. ft. capacity with 1 cooking power
  • Sensor cooking controls adjust time and power automatically
  • Weight and time defrost options for flexible meal prep
  • Instant-on express cooking and kitchen timer functions

Smallest and quietest option with reliable heating for single users and tight spaces, though long-term durability is unpredictable.

Check on Amazon →Opens at amazon.com · affiliate link

Ideal for: Students, single users, and renters with minimal space and heating needs.

The Black+Decker's compact 0.9 cubic foot design is purpose-built for dorms, studios, or anyone with minimal counter space. At 900 watts and the smallest footprint in this lineup, it heats efficiently for single servings and doesn't dominate the kitchen visually. Most owners describe it as quiet and reliable for everyday use, and the price-to-performance ratio is appealing if you have modest heating needs. The push-button door and straightforward controls make it a low-friction daily tool.

Durability, however, is the elephant in the room. Several owners report catastrophic failures within months: one unit sparked and caught fire 30 seconds into reheating a burrito, and another had the door aluminum shell fall off after a few months. The customer service process mirrors the larger Black+Decker model: frustrating phone trees, request loops, and strict proof-of-purchase requirements that can drag on for weeks. Early failure rates and the nightmare warranty experience stand in stark contrast to the Toshiba's overall track record. While the Toshiba also has durability variability, owners who experience problems report faster resolution and generally more cooperative support. If you need microwave capacity sizing to determine the right fit, consider that this model maxes out at 0.9 cu. ft., whereas the larger GE option doubles that space for similar total cost over a longer ownership period.

This works well as a stopgap or backup unit, but treat it as temporary rather than a long-term kitchen anchor.

Pros

  • Compact 0.9 cu. ft. footprint ideal for tight spaces
  • Quiet operation and straightforward push-button controls
  • Low entry cost for basic reheating functionality

Cons

  • Multiple reports of internal failures and sparking after weeks
  • Warranty claims process is lengthy and frustrating
Key features
  • 0.9 cu. ft. capacity with 900-watt cooking power
  • 10 power levels with 30-second express cooking mode
  • 6 pre-programmed buttons for common foods
  • Child safety lock and removable 10.6-inch turntable

How to Choose the Right Microwave for Your Kitchen

Four trade-offs that actually matter when matching a microwaves at costco to your kitchen.

Capacity and Counter Space

Microwave size matters more than specs suggest. A 0.9 cubic foot model handles single plates and small bowls fine; a 1.6 cu. ft. fits full-size dinner plates and larger containers without crowding. The 2.0 cu. ft. option accommodates oversized items and multiple servings at once. Measure your counter depth and height before buying: many microwaves need 3 inches of clearance on each side for airflow. If space is tight, a compact model works, but don't undersize if your household regularly heats large items simultaneously. The difference between 0.9 and 1.6 cu. ft. is small in footprint but significant in practical usability. Consider microwave capacity sizing when deciding between models to avoid buyer's remorse.

Wattage and Heating Speed

Higher wattage heats faster and more evenly. A 900-watt model takes longer than a 1 one for the same task. Most households do fine with 1000-1150 watts for everyday use. The jump to 1200 watts becomes noticeable if you reheat frequently or cook frozen items regularly. Sensor cooking controls that adjust time and power automatically are worth seeking out; they eliminate guesswork and prevent overcooked or undercooked food. Lower-wattage models work fine for light use but may frustrate busy households. If your family heats multiple items daily, prioritize wattage and microwave wattage guide information to understand how power affects your workflow.

Durability and Warranty

Budget models sometimes fail within months, while mid-range options often last 5-10 years if treated normally. Read recent reviews carefully for patterns: if multiple owners report failures in the first year, that's a red flag. Warranty coverage varies significantly; some brands offer hassle-free claims, while others require extensive documentation and create frustrating claim processes. One-year warranties are standard, but the quality of customer service behind that warranty differs greatly. Avoid models with consistently negative durability reports, even if the upfront price is attractive. A microwave that lasts five years costs less per year than one that fails after six months, even at double the initial price.

Control Layout and Noise Level

Simple, illuminated buttons beat complex touchpads for ease of use, especially in low light. Older-style mechanical controls are often more intuitive than modern digital interfaces with multiple nested menus. Noise is underrated as a selection factor; some microwaves hum quietly, while others buzz loudly enough to startle you. If you use the microwave early morning or late night, noise matters. Mute functions are a nice-to-have feature for those sensitive to beeping. Read owner reviews specifically for noise complaints: if several mention a loud buzzing sound, that's a legitimate concern worth considering, not just personal preference. The best ceramic air fryer also emphasizes quiet operation as a selling point, showing that low-noise performance is increasingly expected across kitchen appliances.

Safety and Convenience Features

Child locks are now standard, though quality varies. Some are easy to disable; others require tools or instructions. If you have young children or live in shared spaces, verify the lock is straightforward to manage. Defrost by weight and by time are both useful options for preparing frozen items. Express cooking (add 30 seconds with one button press) saves repetitive menu navigation. Turntables should rotate smoothly and remove easily for cleaning. Anti-slip feet prevent the unit from sliding on smooth countertops: a genuine safety hazard some models overlook. Check whether the manufacturer offers phone support or relies on email loops that drag on for weeks; that matters if something goes wrong.

Frequently asked

Quick answers to the questions readers ask most.

What wattage microwave do I actually need for my household?

For a single person or light use, 900-1000 watts is sufficient. Families and busy households benefit from 1150-1200 watts, which heats faster and more evenly. The difference between 900 and 1200 watts is visible when reheating multiple items or cooking frozen food frequently. Test cooking times in reviews to see if owners of lower-wattage models mention waiting significantly longer than expected: that's a clue you might want more power than you think.

How do sensor cooking controls actually work, and are they worth the extra cost?

Sensor cooking monitors moisture released by food and automatically adjusts cooking time and power to prevent overcooking. Instead of guessing whether something needs 2 or 3 minutes, you press a button and the microwave handles it. Most owners find this eliminates the trial-and-error of reheating different foods, making daily use less frustrating. It's worth paying extra for if you reheat varied items frequently, but unnecessary if you mostly use preset times.

Should I be concerned about durability if a cheap microwave has good reviews?

Good short-term reviews don't guarantee longevity. Some budget models work fine for their first month or two, then fail catastrophically. Look for reviews that mention owner tenure: comments like 'I've had this for 3 years' carry more weight than 'just arrived and works great.' If multiple reviews mention failures within 6-12 months, that's a durability pattern worth heeding, even if the average rating is decent.

Can I fit a full-size dinner plate in every microwave, or do I need to check dimensions first?

No: compact 0.9-1.0 cu. ft. models often can't fit a standard plate flat without overlapping or breaking off a corner. Mid-range 1.2-1.6 cu. ft. units usually accommodate a full plate comfortably. If plate heating is important to your household, check internal dimensions (not just the capacity number) or read reviews where owners mention plate fit directly. It's a simple factor that causes frustration if overlooked.

Is the mute or silence function just a gimmick, or does it actually matter?

For most households, it's secondary, but for early risers, light sleepers, or anyone in a shared space, eliminating beeping sounds can be genuinely valuable. If you've ever been startled by a microwave alarm at 6 a.m., you understand the appeal. It's not essential, but if your schedule or living situation makes noise a factor, it's worth prioritizing a model that offers this feature.
