The LG NeoChef MSER2090S is a large countertop microwave. It has a simple glass touch panel with typical options, like 'Popcorn,' 'Defrost,' and a '+30 seconds' button, as well as controls for the microwave's cooking sensor, which detects steam to make cooking more automatic.
Our Verdict
The LG MSER2090S offers great performance for everyday use. It's a powerful 1200-watt model that heats food quickly and offers enough internal capacity for plates, bowls, or even a full-sized casserole dish. Its responsive glass touch panel makes it easy to program simple cooking settings, and it includes a cooking sensor that automatically adjusts cooking time by detecting steam. That said, it takes more effort to set a lower power level or cook for a specific amount of time. It's reasonably quiet during operation, though plenty of microwaves are quieter.

Popular Microwave Comparisons
The LG NeoChef MSER2090S is a countertop microwave with a very large internal capacity. This 1200-watt model cooks food faster than some microwaves with the same power rating, like the Breville the Smooth Wave. Like the LG LMC0975ST, it has a glass touch panel that is responsive and pleasant to use; however, unlike that model, it also has a cooking sensor that can automatically adjust the cook time, making heating and reheating more hands-off. Similar to the Panasonic NN-SN975S, another very large countertop microwave, setting simple cooking programs is easy, but adjusting the power level and cook time to specific settings takes more time. While it's a reasonably quiet option, many models, such as the Toshiba EM131A5C-BS, are much quieter. It doesn't have a dedicated mute button, but you can silence the controls by holding down the "STOP/CLEAR" and "TIMER/CLOCK" buttons simultaneously for three seconds.

The LG NeoChef MSER2090S is a better microwave than the Panasonic NN-SN68QB for most people. They're both powerful models that heat food quickly, but the LG offers a larger internal capacity and is easier and more convenient to use day to day. It has a glass touch panel which is more responsive than the Panasonic's membrane touch panel. While it's easy to start simple cooking tasks, like heating for three minutes at full power, on either, the LG makes it a little easier to adjust the power or set a more specific cook time. That said, the Panasonic is quieter, which you may prefer if noise is a concern.
The LG NeoChef MSER2090S and the Samsung MS19DG8500SR are both large countertop microwaves. While the LG offers better overall performance, you may prefer either depending on your priorities. Choose the LG if you're looking for a microwave that cooks faster, or if the design of the controls is important to you, since the LG's glass touch panel is more responsive and pleasant to use. Go for the Samsung if noise is a concern for you, as it offers quieter operation.
The Sharp SMC2266KS and the LG NeoChef MSER2090S are both powerful microwaves, and you may prefer one over the other depending on your priorities. Both microwaves are large models, but the Sharp has a little more internal capacity, and it makes less noise during operation. The LG's glass touch panel offers more responsive controls, but while it's a little easier to adjust the power or set a specific cook time, you can start a simple program with a single button press on the Sharp. The Sharp is also quieter.
The LG NeoChef MSER2090S is a better microwave than the Toshiba EM131A5C-BS for most people. It's a bit more powerful and offers a much larger internal capacity, so you can use it to heat larger dishes, like a lasagna or casserole. The LG has a glass touch panel, which is more responsive than the Toshiba's membrane touch panel. It's easier to set simple cooking programs with the Toshiba, but slightly easier to dial in the cooking settings with the LG. The Toshiba is quieter, however, so you may prefer it for that reason, or if you don't need as much cooking capacity.
Test Results
If you're looking for a comparably powerful microwave with a much smaller footprint, consider the Panasonic NN-SF57RM.
This microwave is reasonably quiet, but if you want something quieter, consider the Sharp SMC2266KS or the Sharp SMC1162KS.
Microwaves all perform similarly in terms of heating uniformity, so you won't notice a difference between models. Instead, heating evenness depends on the type and amount of food you're heating, as well as where it's placed in the cooking chamber. To learn more, read our investigation into microwave performance.
