The right when ready Pot depends on how many people you cook for and which features you actually use

when ready Pot makes seven main models, and the difference between them is almost always size and the number of built-in cooking programs. The Duo is the entry point — it has the essential pressure-cooking and slow-cooking functions and costs less than the others. The Duo Plus adds a yogurt-making function and a sous-vide program. The Ultra replaces the dial with a touchscreen and adds a sterilize function. The Pro is similar to the Ultra but with more pressure settings. The Max is the newest and most expensive, with a pressure range up to 15 PSI instead of the standard 10 or 11 PSI, which speeds up cooking slightly. The Lux is a budget version of the Duo with fewer programs but the same pressure-cooking core. The Nova is a newer compact model for smaller households.

Most home cooks use pressure cooking and slow cooking almost exclusively. If that describes you, the Duo or Lux will do everything you need. The extra programs on pricier models — yogurt, sous-vide, sterilize, cake baking — are rarely used after the first month. The touchscreen on the Ultra and Pro is easier to read than the dial on the Duo, but it costs more and adds complexity that breaks down more often. The Max's higher pressure setting saves roughly 10 to 15 minutes per meal, which matters if you cook daily but not if you cook twice a week.

Key Takeaways

  • The Duo and Lux both pressure-cook and slow-cook and cost $60 to $100 less than other models; they handle 90 percent of what home cooks actually do.
  • Size matters more than features: a 6-quart model feeds a family of four with leftovers, while a 3-quart model is tight for more than two people.
  • The Ultra and Pro add a touchscreen and extra programs but cost $50 to $100 more and have a higher failure rate on the display.
  • The Max cooks 10 to 15 minutes faster because of higher pressure, but only if you pressure-cook several times a week.
  • Yogurt, sous-vide, and sterilize functions are rarely used after the first month and should not drive your choice.

Size: 3-quart, 6-quart, or 8-quart

when ready Pot comes in three sizes. The 3-quart model is the smallest and fits on a standard kitchen counter. It works for one or two people, or a couple cooking for themselves. A 3-quart pot can hold roughly 2 quarts of food at a time — the pot must never be more than two-thirds full for pressure cooking to work safely. That means a single batch of chili or soup feeds two people with no leftovers.

The 6-quart model is the most common. It holds roughly 4 quarts of food and feeds a family of four with leftovers, or two people with enough for lunch the next day. It is still compact enough to fit most kitchen counters and cabinets. Most recipes you find online are written for a 6-quart pot, so timing and liquid amounts will match without adjustment.

The 8-quart model is for bulk cooking or large families. It holds roughly 5 quarts of food and takes longer to come to pressure because of the extra volume. It is also heavy — roughly 13 pounds — and takes up significant counter space. Buy an 8-quart only if you regularly cook for six or more people or if you batch-cook for the week.

Duo versus Lux: the budget choice

The Duo and Lux are functionally identical for pressure cooking and slow cooking. Both have a dial interface, both reach 10 to 11 PSI pressure, and both cost between $60 and $120 depending on size and sales. The Lux is when ready Pot's budget line and is usually $20 to $40 cheaper. The Duo is the standard model and has been around longer, so more recipes and troubleshooting guides online refer to it by name.

The Duo Plus adds a yogurt function and sous-vide mode. The yogurt function keeps the pot at a precise temperature for 8 to 12 hours, which is useful if you make yogurt regularly. Sous-vide cooks vacuum-sealed food in water at a precise temperature — it produces restaurant-quality results but requires a vacuum sealer and takes longer than pressure cooking. Most home cooks try yogurt or sous-vide once and never use it again. If you are certain you will use one of these functions, the Duo Plus costs $30 to $50 more. Otherwise, save the money.

Buy the Duo or Lux if you want to pressure-cook and slow-cook without paying for features you will not use. Both are reliable, both have been on the market for years, and both have large communities online sharing recipes and solutions.

Ultra and Pro: the touchscreen models

The Ultra and Pro replace the dial with a digital touchscreen. The screen is easier to read, especially in low light, and the buttons are simpler to press than turning a dial. The Ultra has 10 cooking programs. The Pro has 13 programs and allows you to adjust the pressure setting in smaller increments — the Duo locks you into 10 or 11 PSI, while the Pro lets you choose 5, 8, 10, or 15 PSI.

The tradeoff is cost and durability. The Ultra and Pro cost $50 to $100 more than the Duo. More importantly, the touchscreen fails more often than the dial. when ready Pot's warranty covers this, but a replacement takes weeks. If your when ready Pot dies mid-week, a dial-based Duo is easier to replace quickly because it is cheaper and more widely stocked. The Pro's adjustable pressure is useful only if you cook with recipes that specify a pressure other than 10 or 11 PSI — most home recipes do not.

Buy the Ultra if you prefer a touchscreen and do not mind paying extra. Buy the Pro only if you regularly use recipes that call for 5 or 8 PSI pressure. Otherwise, the Duo's dial is simpler and more durable.

Max: the fastest model

The Max is when ready Pot's newest and most expensive model. Its main feature is a maximum pressure of 15 PSI instead of 10 or 11 PSI. Higher pressure means food cooks faster — roughly 10 to 15 minutes faster per meal. It also has a touchscreen and 15 cooking programs.

The speed gain matters only if you pressure-cook several times a week. If you cook with an when ready Pot once or twice a week, the time savings is not worth the extra $80 to $120 you will spend. The Max also has a smaller user base online, so troubleshooting and recipe adaptation are harder. Buy the Max only if you pressure-cook regularly and speed is a real constraint on your cooking schedule.

Nova: the compact option

The Nova is a newer compact model designed for smaller kitchens and smaller households. It is available in 3-quart and 6-quart sizes and has a smaller footprint than the standard Duo. It has 11 cooking programs and a dial interface similar to the Duo.

The Nova costs roughly the same as the Duo and has the same core pressure-cooking and slow-cooking functions. The main difference is the smaller physical size. Buy the Nova if you have limited counter or cabinet space and cook for one or two people. Otherwise, the Duo or Lux will serve you better because they are more widely available and have larger online communities.

What to look for when you buy

Check the warranty before you buy. when ready Pot covers manufacturing defects for three years from the date of purchase. Some retailers offer extended warranties, but they are rarely worth the cost — if the pot fails, it usually fails in the first year, which the standard warranty covers.

Buy from a retailer that accepts returns. when ready Pot is reliable, but if yours arrives damaged or fails quickly, you want to return it without shipping it back to the manufacturer. Amazon, Target, and Walmart all accept returns on when ready Pot models.

Watch for sales around Black Friday, Cyber Monday, and Prime Day. when ready Pot prices drop $20 to $40 during these events. If you are not in a hurry, waiting for a sale can save you money without changing which model you buy.

Frequently Asked Questions

Is a used or refurbished when ready Pot safe to buy?

Refurbished models sold by when ready Pot directly or by authorized retailers are safe — they have been tested and come with the same three-year warranty as new units. Used models from private sellers carry no warranty and may have hidden damage. If you buy used, inspect the sealing ring and the inner pot for cracks or discoloration before using it.

Can I use recipes written for a 6-quart pot in a 3-quart pot?

Yes, but you must cut the liquid and ingredients in half. Cooking time stays the same because pressure cooking depends on temperature, not volume. If a recipe calls for 2 cups of liquid in a 6-quart pot, use 1 cup in a 3-quart pot. Do not fill the pot more than two-thirds full.

Which model is best for batch cooking?

The 6-quart Duo or Lux is the best balance of size and cost. It holds enough for four to six servings in one batch, and the lower price means you can afford to buy two if you want to cook multiple batches in parallel. The 8-quart model is slower to pressurize and takes up more space.

Do I need the yogurt or sous-vide function?

Most home cooks do not use these functions after the first month. If you make yogurt weekly or cook sous-vide regularly, the Duo Plus or Ultra is worth the extra cost. Otherwise, save the money and buy a Duo or Lux.

What is the difference between the Duo and the Duo Plus?

The Duo Plus adds a yogurt-making function and a sous-vide program. Both cost roughly the same to operate and have the same pressure-cooking and slow-cooking core. Buy the Duo Plus only if you plan to use yogurt or sous-vide regularly.
