LG MSER1590B Reviews & Ratings by Customers and Consumer Reports

Designed for households that want a full-featured countertop microwave without committing to built-in installation, the LG MSER1590B 22 Inch Countertop Microwave is best suited to busy kitchens where speed, consistent heating, and straightforward daily usability matter more than ultra-compact sizing. As an appliance specialist, I view this model as a strong “primary microwave” for apartments, condos, and family kitchens—especially for users who reheat frequently, cook packaged foods, and want more control than basic dial-and-timer units. In real-world use, LG tends to prioritize even cooking performance and intuitive controls, and this unit follows that expectation. The control layout is typically easy to learn, with clear presets that reduce guesswork for common tasks like reheating leftovers or melting and softening. For most buyers, the practical benefit is consistency: fewer cold centers, less overcooked edges, and less need to stop and stir multiple times. The 22-inch class footprint also generally provides a more accommodating cavity than compact models, which helps when rotating larger plates or using taller microwave-safe containers. From a day-to-day ownership standpoint, countertop microwaves in this category are expected to be relatively low-maintenance, and the LG MSER1590B 22 Inch Countertop Microwave should meet that standard. A stable door feel, predictable button response, and a solid turntable system are the kinds of durability cues professionals look for, because they correlate with long-term reliability in high-use kitchens. Noise levels are typically moderate for the category: you’ll hear the fan and turntable operation, but it shouldn’t dominate an open-concept space unless you’re particularly sensitive to appliance sound. The main limitations are the ones inherent to larger countertop units. It may not suit buyers with shallow counters, tight upper-cabinet clearance, or those trying to minimize visual presence in a small kitchen. Like many modern microwaves, the audible end-of-cycle alerts can also be more noticeable than some users prefer, and the exterior finish may show fingerprints depending on lighting and cleaning habits. Verdict: LG’s MSER1590B is a well-judged choice for shoppers who want a capable, everyday countertop microwave with a more spacious feel and dependable usability—whether in a U.S. kitchen or a Canadian condo where countertop space is planned carefully. Those needing a truly compact unit, or who want a built-in look, may want to consider alternative form factors.
