What to Look for When Buying Instant Pots
1. Budget & Price Range
When shopping for an Instant Pot, your budget is often the first and most decisive factor. The price difference between the Duo and Duo Plus may seem modest at first glance—typically ranging from $20 to $50 depending on sales and retailer—but it can add up, especially if you’re comparing multiple units or bundling with accessories. Understanding what you’re paying for helps determine whether the extra cost delivers proportional value.
The Instant Pot Duo generally retails between $79 and $99, making it one of the most affordable entry-level multi-cookers in the Instant Pot lineup. It’s ideal for budget-conscious buyers who want core functionality without frills. In contrast, the Duo Plus typically ranges from $99 to $129, placing it in the mid-tier category. While this might seem like a small jump, it reflects tangible improvements in design, safety, and user experience.
Consider your long-term usage. If you plan to use your Instant Pot several times a week—for everything from weeknight dinners to weekend meal prep—the added features of the Duo Plus may pay for themselves in convenience and durability. On the other hand, if you’re only planning occasional use or are testing the waters with pressure cooking, the standard Duo offers excellent value for the price.
2. Performance Specifications
Performance is where the Duo and Duo Plus begin to diverge meaningfully. Both models operate at a standard pressure of 10.15–11.6 psi (pounds per square inch), which is sufficient for most home cooking tasks like tenderizing meats, cooking beans, and steaming vegetables. However, the Duo Plus introduces a higher wattage motor—1000 watts compared to the Duo’s 800 watts—which translates to faster heat-up times and more consistent pressure building.
This difference becomes noticeable when cooking dense or large-volume meals. For example, a whole chicken or a pot of dried beans will reach pressure faster in the Duo Plus, reducing overall cooking time by 5–10 minutes. While this may not seem like a major advantage, over dozens of uses, those minutes add up—especially for time-strapped families.
Additionally, the Duo Plus features improved temperature control algorithms, which help maintain more stable internal temperatures during slow cooking and sautéing. This results in more even browning and reduced risk of scorching, a common complaint among Duo users when using the sauté function for dishes like risotto or caramelized onions.
Another performance-related upgrade is the inclusion of a “Yogurt” button with customizable temperature settings on the Duo Plus. While the standard Duo also has a yogurt function, it lacks the precision control needed for advanced fermentation techniques, such as making Greek-style yogurt or kefir. For home dairy enthusiasts, this feature alone can be a game-changer.
3. Build Quality & Durality
Build quality is a critical but often overlooked aspect of any kitchen appliance. Both the Duo and Duo Plus feature a brushed stainless steel exterior and a removable 304-grade stainless steel inner pot, which are durable, non-reactive, and easy to clean. However, the Duo Plus incorporates several design enhancements that improve longevity and user safety.
One of the most significant upgrades is the redesigned lid and sealing ring system. The Duo Plus uses a more robust silicone sealing ring that is less prone to warping or retaining odors over time. It also includes a redesigned steam release handle with a more intuitive push-button mechanism, reducing the risk of accidental burns during quick releases. In contrast, the Duo’s steam release valve requires a twist-and-turn motion, which some users find less ergonomic, especially with wet or greasy hands.
The control panel on the Duo Plus is also more durable, with tactile, dome-shaped buttons that provide better feedback and are less likely to wear out after repeated use. The Duo’s flat membrane buttons, while functional, can become less responsive over time, particularly if food residue accumulates around the edges.
Internally, the Duo Plus features a reinforced heating element and improved thermal insulation, which not only enhances cooking efficiency but also reduces the risk of overheating during extended use. These subtle but important improvements contribute to a more reliable and long-lasting appliance.
4. Features & Functionality
Functionality is where the Duo Plus truly shines. While both models are marketed as “7-in-1” appliances—capable of pressure cooking, slow cooking, rice cooking, steaming, sautéing, yogurt making, and warming—the Duo Plus offers enhanced precision and customization across these modes.
The most notable upgrade is the addition of a “Sauté” function with adjustable temperature settings. On the standard Duo, the sauté mode operates at a single high heat, which can lead to uneven cooking or burning if not closely monitored. The Duo Plus, however, allows users to select between “Normal,” “More,” and “Less” heat levels, giving greater control for delicate tasks like reducing sauces or toasting spices.
Another key feature is the “Delay Start” function, which is more robust on the Duo Plus. While both models allow you to schedule cooking up to 24 hours in advance, the Duo Plus includes a “Keep Warm” override that automatically activates after the cooking cycle ends, ensuring food stays at a safe temperature without overcooking. This is particularly useful for meal preppers who want to cook overnight or during work hours.
The Duo Plus also includes a “Sterilize” function, which uses high-pressure steam to sanitize baby bottles, utensils, or jars—ideal for new parents or home canners. This feature is absent on the standard Duo, which limits its utility for hygiene-focused tasks.
Additionally, the Duo Plus supports a wider range of cookware compatibility. Its improved heating element allows it to work more effectively with thicker-bottomed pots and pans when used in sauté mode, reducing hot spots and improving browning.
5. Brand Reputation
Instant Pot has built a stellar reputation over the years for innovation, reliability, and customer-centric design. The brand consistently ranks among the top performers in consumer reviews for multi-cookers, with high marks for ease of use, versatility, and post-purchase support. Both the Duo and Duo Plus benefit from this strong brand equity, but the Duo Plus, as a newer model, reflects the company’s ongoing commitment to refinement and user feedback.
One area where Instant Pot excels is in community engagement. The brand actively listens to customer suggestions and incorporates them into product updates. For example, the improved lid design and steam release mechanism on the Duo Plus were direct responses to user complaints about the earlier Duo model. This responsiveness enhances trust and ensures that newer models address real-world pain points.
Moreover, Instant Pot’s ecosystem extends beyond hardware. The company offers a robust library of recipes, video tutorials, and a mobile app (Instant Pot Smart) that supports Bluetooth connectivity on select models. While neither the Duo nor Duo Plus is Bluetooth-enabled, the app still provides valuable guidance for beginners and advanced users alike.
6. Warranty & Support
Warranty and customer support are essential considerations, especially for appliances that see frequent use. Both the Duo and Duo Plus come with a standard 1-year limited warranty, which covers defects in materials and workmanship under normal household use. This is fairly typical for small kitchen appliances, though some competitors offer longer coverage.
However, Instant Pot’s customer service has received mixed reviews over the years. While many users report prompt and helpful responses, others have experienced delays in replacement parts or difficulty navigating the warranty claim process. The Duo Plus, being a newer model, may benefit from improved support infrastructure, but this isn’t guaranteed.
To maximize your protection, consider purchasing an extended warranty through third-party providers like Amazon or Best Buy, especially if you plan to use the appliance heavily. Additionally, registering your product online can streamline future support requests and ensure you receive firmware updates or safety notifications.
7. Size & Portability
Size and portability matter more than you might think—especially if you have a small kitchen or plan to store the appliance in a cabinet. Both the Duo and Duo Plus are available in 3-quart, 6-quart, and 8-quart capacities, with the 6-quart model being the most popular for average households.
The Duo Plus is slightly heavier and bulkier due to its enhanced internal components and sturdier build. For example, the 6-quart Duo weighs approximately 11.5 pounds, while the Duo Plus comes in at around 12.8 pounds. This difference is minimal for most users but could be a factor if you plan to move the appliance frequently or have limited counter space.
Both models have the same footprint—about 13.5 inches in diameter—so they fit comfortably on standard countertops. However, the Duo Plus’s taller lid design may require slightly more vertical clearance when opening, which is worth noting if you store it under cabinets.
Portability is also influenced by handle design. The Duo Plus features slightly larger, more ergonomic handles with a textured grip, making it easier to lift and carry when full. The Duo’s handles are functional but less comfortable, especially with heavy loads.
8. User Reviews & Ratings
User reviews provide invaluable insights into real-world performance. Across major retailers like Amazon, Walmart, and Target, both the Duo and Duo Plus maintain high ratings—typically 4.6 to 4.8 out of 5 stars—but the Duo Plus consistently edges out the Duo in overall satisfaction.
Common praises for the Duo include its affordability, simplicity, and reliable pressure cooking performance. Users appreciate its straightforward interface and ease of cleaning. However, frequent criticisms center around the sauté function’s lack of control, the flimsy steam release valve, and the tendency for the sealing ring to retain odors.
The Duo Plus, on the other hand, receives acclaim for its improved build quality, enhanced functionality, and better user experience. Reviewers highlight the adjustable sauté settings, intuitive steam release, and overall sturdiness as major upgrades. Some users note that the higher price is justified by the added convenience and durability.
That said, a small percentage of Duo Plus users report issues with the control panel becoming unresponsive after several months of use—a rare but notable concern. This underscores the importance of purchasing from reputable retailers with strong return policies.

Common Buying Mistakes to Avoid
❌ Mistake: Choosing Based Solely on Price
Why it’s bad: Opting for the cheapest model without considering long-term use can lead to frustration. The standard Duo, while affordable, lacks the refined features and durability of the Duo Plus, which may result in more frequent replacements or dissatisfaction over time.
What to do instead: Evaluate your cooking frequency and needs. If you plan to use the appliance regularly, the Duo Plus’s upgrades often justify the higher cost. Consider the total cost of ownership—including potential repairs or replacements—rather than just the upfront price.
❌ Mistake: Ignoring Capacity Needs
Why it’s bad: Selecting a 3-quart model for a family of four—or an 8-quart for a single person—can lead to inefficient cooking or wasted space. Overfilling or underutilizing the pot affects performance and safety.
What to do instead: Match the capacity to your household size. A 6-quart model is ideal for most families, while 3-quart suits singles or couples, and 8-quart is best for large batches or entertaining.
❌ Mistake: Overlooking Safety Features
Why it’s bad: Pressure cookers involve high heat and steam, making safety paramount. Older or lower-end models may lack modern safeguards like lid locks, pressure sensors, or automatic shut-off.
What to do instead: Always choose models with multiple safety mechanisms. Both the Duo and Duo Plus include 10+ safety features, but the Duo Plus’s improved steam release and lid design offer added peace of mind.
❌ Mistake: Not Reading User Reviews
Why it’s bad: Marketing materials highlight strengths but often omit real-world flaws. Skipping user feedback can lead to unpleasant surprises, such as poor build quality or difficult cleaning.
What to do instead: Spend time reading verified purchase reviews on trusted platforms. Look for recurring themes—both positive and negative—to get a balanced perspective.
❌ Mistake: Forgetting About Accessories
Why it’s bad: The base model may not include essential accessories like extra sealing rings, steamer baskets, or silicone lids, which can add $20–$40 to your total cost.
What to do instead: Check what’s included in the box and consider purchasing a starter kit. The Duo Plus often comes with more accessories, adding to its value.
❌ Mistake: Buying Without a Return Policy
Why it’s bad: If the appliance doesn’t meet your expectations or arrives defective, a poor return policy can leave you stuck with a unusable product.
What to do instead: Purchase from retailers with generous return windows (e.g., Amazon, Costco, or Target). Avoid third-party sellers with unclear policies.
