The Panasonic NN-SU158S is a 1.9 cu ft, 1000W over-the-range microwave in black at $380, backed by Panasonic's reliable appliance reputation. With only 12 reviews, buyer data is too thin to assess confidently, but the specs are competitive and the brand carries genuine credibility in the microwave category.
Buyers who trust Panasonic's microwave heritage and want a large 1.9 cu ft interior with touchscreen controls in a black finish. Panasonic's inverter cooking technology, if present in this model, is a meaningful differentiator worth confirming.

Overview
Panasonic is one of the most respected microwave brands in the world, with a long history of reliable residential and commercial units. The NN-SU158S brings a 1.9 cu ft interior, one of the larger available in OTR models, and 1000W output with 10 power levels to a $380 price point. Touchscreen controls and a black color fit kitchens with dark appliance finishes.
At 12 reviews averaging 4.2 stars, the buyer sample is too small to draw strong conclusions. Panasonic's OTR lineup has historically performed well in reliability surveys, but that brand-level track record doesn't replace model-specific data. The absence of width information in the available specs is also worth noting, buyers should confirm the unit fits their specific OTR cutout before ordering.
For buyers who know they want a Panasonic microwave and need OTR form factor, this unit delivers the brand's core strengths. For buyers doing pure spec-and-price comparisons, the lack of width data and thin review count make it harder to evaluate fairly against well-documented competitors in the same price range.

Performance notes
At 1000W with 10 power levels, this unit handles standard reheating, defrost, and cooking tasks. The 1.9 cu ft interior is generous for an OTR model and accommodates larger dishes. Touchscreen controls are standard for this class. Width is not listed in available data, this is the most critical spec to confirm before purchasing, as OTR installation depends entirely on matching the unit's width to the mounting space. The black color is listed without a stainless option for this ASIN. Panasonic microwaves are known in the industry for consistent heating performance, often attributed to their inverter technology where applicable.
What buyers say
The 4.2-star average from 12 reviews suggests buyers are satisfied, but 12 reviews provides a weak statistical foundation. A single highly positive or negative experience can shift the average significantly at this sample size. The Panasonic brand name carries inherent positive sentiment among buyers familiar with their microwave lineup, and that brand trust is likely influencing purchase decisions here more than model-specific review data.
What makes Panasonic microwaves different from other brands?
Panasonic is particularly known for its inverter microwave technology, which delivers continuous cooking power at lower settings rather than cycling on and off like conventional microwaves. This results in more even cooking and better results with delicate foods. Whether this specific OTR model uses inverter technology should be confirmed on the product detail page.
The width is not listed, how do I know if this fits my kitchen?
This is the most important question to answer before purchasing. Over-the-range microwaves must match your existing mounting bracket width and cabinet opening. Contact Panasonic directly or check the product's full specification sheet to confirm the width before ordering. Most OTR units are 29.75-30 inches wide.
Is $380 a reasonable price for a Panasonic OTR microwave?
It is within the mid-range for OTR microwaves. The Panasonic name typically commands a small premium over generic brands. For comparison, the BLACK+DECKER EM044KB19 offers a similar 1.9 cu ft interior with convection at $343 and has over 12,000 reviews. Whether the Panasonic brand and any inverter technology advantages justify the difference depends on your priorities.
