The LG LMC0975ST is a small, budget-friendly inverter microwave. Most of its buttons are hidden when the door is closed, giving it a sleek look. Instead of a handle or button, you open it by pulling on the door. It has basic features like a popcorn button and defrost function, but you can't mute the controls, and it doesn't have a steam sensor.

    Popular Microwave Comparisons

    The LG LMC0975ST is a small inverter microwave. While it has lots of automatic programs for cooking, reheating, and defrosting, it doesn't have a steam sensor, and you can't mute the controls. It stands out for its design, which hides most buttons when the door is closed. If you want a small microwave with a mute option, you might like the Insignia NS-MW09SS8 or the Toshiba EM925A5A-BS instead. The Toshiba EM131A5C-BS is an option with a steam sensor, although it's not quite as small.
