LG MSER1590S Reviews & Ratings by Customers and Consumer Reports

Designed for households that want a premium countertop microwave without stepping up to a built-in installation, the LG MSER1590S 22-inch countertop microwave is best suited to busy home cooks, small families, and condo or apartment kitchens where speed and consistency matter as much as footprint. As an appliance specialist, I’d position this model as a “daily-driver” microwave that prioritizes even heating, intuitive operation, and a clean, modern exterior that fits well in contemporary North American kitchens, including many Canadian condo layouts where counter space is at a premium. In real-world use, LG MSER1590S stands out for its strong overall cooking performance in the category. It handles common tasks—reheating plated meals, softening butter, warming beverages, and cooking packaged foods—with reliable results and fewer hot-and-cold zones than many basic countertop units. That consistency matters because it reduces the need to stop, stir, and restart, which is often the difference between a microwave that feels “good enough” and one that feels genuinely dependable day to day. Usability is another strength. Controls are typically straightforward for this class, and the door, handle, and turntable system are the kinds of touchpoints that influence long-term satisfaction. The stainless-look finish presents a more upscale appearance than painted cabinets and tends to be easier to keep looking presentable with routine wiping, especially in high-traffic kitchens. As with most 22-inch countertop microwaves, there are practical limitations to consider. It may not suit buyers who routinely heat extra-large casserole dishes or oversized cookware, since countertop models in this size range can be constrained by interior geometry even when the exterior footprint feels generous. Also, like many microwaves with reflective finishes, fingerprints and smudges can show, so it rewards owners who prefer quick, regular cleaning. Verdict: LG delivers a well-rounded countertop microwave in LG MSER1590S that emphasizes consistent heating, everyday convenience, and a polished kitchen-friendly design. It’s an excellent fit for users who want dependable reheating and cooking performance in a refined countertop format, while those needing maximum interior clearance for very large dishes may want to consider a larger-capacity style or a built-in solution.
