Samsung NE59M6850 review: Samsung's Flex Duo electric stove is solid, but not stellar

The $1,600 Samsung NE59M6850's best feature is the Flex Duo insert, which creates a double oven in which you can cook at different temperatures.

Samsung's Flex Duo insert has the power to elevate so-so models like the $1,600 Samsung NE59M6850 to the top of your wish list. The Flex Duo is a divider you put into the oven's single cavity that divides it into two separate cooking zones, so you have the flexibility of being able to cook two dishes at different temperatures at the same time without the investment of a built-in double oven.

The Good

The $1,600 Samsung NE59M6850 electric range comes with Samsung's Flex Duo insert, a divider that creates two different cooking zones within the single oven cavity. The easy-to-use stove displayed decent cooking performance in lab tests. And you can connect the stove to Wi-Fi so you can preheat the oven, even if you're away from home.

The Bad

The stove is a bit on the slow side when it comes to length of time to perform basic tasks like boiling and broiling.

The Bottom Line

The Samsung NE59M6850 is a good pick if you're in the market for an electric range that can adapt to your baking needs. But shop around if you don't need a double oven.

If you take away the Flex Duo insert from the Samsung NE59M6850, you're left with an appliance that's good, but not great. Its cooking times and performance during testing were decent, even if they lagged behind what we've seen with other ranges. The stove's ability to connect to Wi-Fi is also a useful feature, but it's not a must-have. The Samsung NE59M6850 is a good choice if you need the flexibility that comes with Flex Duo, especially since this model is one of the cheaper ones that includes this feature. But shop around if you don't need a double oven.

The Samsung NE59M6850 is a black stainless steel, 30-inch wide electric range. The smooth cooktop is equipped with four burners and a warming zone to keep dishes ready-to-serve. The oven cavity, which contains 5.9 cubic feet of space, has two convection fans in the back wall which circulate hot air to bake your food faster and more evenly.

The black stainless steel is a nice alternative to the ever-present traditional stainless steel finish we see on appliances. The overall design is simple and unassuming, so the range will probably look fine with other appliances in a similar finish. The most distracting aspect is the control panel, which has a lot of buttons to control the oven when you use the Flex Duo divider to split the oven into an upper and lower cavity.

To turn the single oven cavity into two different cooking zones, you slide the Flex Duo insert onto the fifth oven rack. With the insert in place, you can set different temperatures for each section and cook dishes simultaneously -- useful when you have to cook a lot of food at once.

You can also use the Flex Duo insert if you don't want to use the entire oven to cook one dish; for example, you could use just the top cavity to heat a frozen pizza rather than heating the whole oven. And you can use the oven door two ways: You can open the entire door or, when the Flex Duo divider is inserted, you can open just the top portion of the oven.

The range can also connect to Wi-Fi to give you some limited ability to control the appliance through Samsung's app. Once you connect the range to Wi-Fi (an easy process through which the app guides you), you can use the app to preheat your oven remotely and check to see if you accidentally left a burner on. This is a useful feature if you want to have a hot oven when you get home or suspect that you might have left on a burner. However, you have to make sure you've enabled the Samsung NE59M6850 to receive commands through the app before you leave the house. And you can't control the cooktop through the app -- you can only see if burners are use. 


The Samsung NE59M6850 was a decent cooker during tests, but none of the results were outstanding. Rather, this oven landed squarely in "just OK" territory.

Let's start with a look at how long it took the Samsung NE59M6850 to boil 112 ounces of water as compared to similar electric stoves :

Note: Time to achieve rolling boil, in minutes

It took an average of 12.37 minutes for the Samsung NE59M6850 to boil a pot of water, which is slower than other electric ranges. Still, the time was at least an improvement over the Samsung NE59J7850WS, an older version of the stove that took an average of 13.1 minutes to boil the same amount of water.

It also took longer to broil burgers in this oven than others we've tested. These are the average times it took to bring six hamburger patties to an internal temperature of 145 degrees Fahrenheit.

Note: Time to achieve 145 degrees F, in minutes

The Samsung NE59M6850 was nearly a minute slower than the fastest broiler we've tested, the Kenmore 97723. But the burgers were still juicy by the time all six patties reached the target temperature, which made up for the slower cook times.

We also tested the Samsung NE59M6850's convection fans by baking two baking sheets of biscuits on different rack levels in the oven. The oven was good at browning the biscuits across each sheet to an even level, but the sheet of biscuits that baked on a higher level were more brown than the lower biscuits. 


The pictures show two sheets of biscuits that were baked at the same time, but on different rack levels. The biscuits on the top baked on a higher level than the biscuits in the bottom photo.

Final thoughts

If you want the convenience of a double oven without committing to the space (or price) that two ovens require, than the Samsung NE59M6850 is a solid pick. Plus, it's one of the least expensive electric models that Samsung offers with Flex Duo. But if you don't need two ovens for cooking, consider the Samsung NE59J7630SB or  GE PB911SJSS, two electric ranges with great performances and good prices.
