Insignia NS-MW09SS8 Microwave Review

Tested using Methodology v1.0
Reviewed Jul 10, 2024 at 10:13 am

The Insignia NS-MW09SS8 is a small, budget-friendly countertop microwave. While it lacks some bells and whistles you find on more expensive microwaves, like a steam sensor, it has the functions you'd expect on a microwave, like a defrost mode, and you can also mute the controls, which isn't always a given.

Our Verdict

N/A Power

The Insignia NS-MW09SS8 is a 900-watt microwave and isn't the fastest. Most 1000-watt microwaves can heat your food a bit faster.

Pros
  • Has a mute function.
  • Compact design.
Cons
  • Somewhat slow.
  • No steam sensor.

Differences Between Sizes And Variants

This microwave comes in Black (NS-MW09BK0) or Stainless Steel (NS-MW09SS8). We tested it in 'Stainless Steel,' and you can see the labels for the unit we tested here and here.

If you come across another variant, let us know in the comments, and we'll update our review.

Compared To Other Microwaves

The Insignia NS-MW09SS8 is a small countertop microwave. It's a budget-friendly option that has a mute function, which gives it an edge over some other small microwaves, like the Cuisinart CMW-70 and the LG LMC0975ST. However, it doesn't have a steam sensor, which would allow the microwave to automatically calculate the cook time. If you want a small microwave with that feature, the Toshiba EM131A5C-BS is a bit bigger but comes equipped with a steam sensor.

It has a small cooking chamber, so it's best suited for smaller containers like mugs and bowls. The light inside isn't very bright, so it can be difficult to see into.

The microwave has simple controls. It's easy to start a 30-second cycle with one button push, and it has a defrost function as well as programs for specific foods like 'Pizza,' 'Popcorn,' and 'Beverage.' It doesn't have a steam sensor, so you always have to manually select the cooking time or input the weight of your food. However, it has a mute function, so you can switch off the end-of-cycle buzzer.

Microwaves all perform similarly when it comes to evenly heating food in shallow dishes. Evenness depends on factors like what kind of food you're heating, in what amount, and what container you're using.

Like with shallow dishes, all microwaves heat food in deep dishes similarly evenly. Evenness depends on what food you're heating, how much of it there is, and in what container, instead of which microwave you're using. Check out our investigation into microwave performance here.
