Toshiba Black Mirror MW3-EM20PF(MB) 20L 800W digital solo microwave

The essentials

If you’re looking at a compact solo microwave for everyday reheating, the Toshiba Black Mirror MW3-EM20PF(MB) is aimed squarely at convenience. It’s a 20L, 800W countertop model with a mirrored black door finish, a digital display, and controls designed to be straightforward—no fancy cooking modes required.

On paper, this one leans practical: you get 11 power levels, one-touch express cooking (from 1 second to 6 minutes), plus 6 auto menus and a defrost function. It’s the sort of microwave that fits well where space is tight, such as a small kitchen, student flat, or caravan.

Worth noting, though: “solo” microwaves are built for microwave cooking and reheating, not for grilling or combination-style cooking. If you regularly want those styles, this can feel limited.

What stands out day to day

The experience here is mostly about speed and control rather than complexity.

The one-touch express cook approach is handy when you want to get food moving immediately—think of pressing a time-based option for a mug of hot chocolate or a quick warm-up for a slice of pizza. Because time selection ranges from very short bursts (starting at 1 second) up to 6 minutes, it covers the “oops, forgot to take it out” moments as well as typical reheating.

Then there’s the digital display and electronic panel control. If you prefer dialing in timing precisely, you can control cooking time in the 1 to 100 minutes range (which is more than most people realistically use day-to-day, but reassuring if you batch something).

Power levels, menus and defrost

The Toshiba uses 11 power settings, which is a bigger spread than you usually see on very basic entry microwaves. That matters because different foods benefit from different intensity—popcorn and hot drinks often don’t need the same power as potatoes or frozen vegetables. With more levels, you’re less likely to overdo the edges while the centre catches up.

You also get 6 auto menus, described as preset recipes. Auto menus can be genuinely useful for consistent results with common items, particularly when you don’t want to think about power and time.

Defrost is another key part of the offer. The listing mentions defrost by weight and time, with the idea of even defrosting without overheating. In reality, defrosting still depends on what you’re thawing and how thick/frozen it is, but this gives you two sensible routes rather than forcing one method.

Size and design that suits smaller spaces

The model is positioned as space-saving with a compact footprint, backed by a 20L capacity. In smaller households, that’s often the sweet spot: enough space for a typical plate or 9-inch pizza, while not eating up worktop area.

It’s also designed with an aesthetic angle: a mirrored black finish with a contemporary “mirror door” look, along with described features like textured buttons and precise knobs. If you care about kitchen styling (even a little), this is meant to fit in rather than look purely functional.

A practical detail mentioned is that it’s designed to be suitable for 9-inch pizza—so if that’s your usual size, it’s one less thing to worry about.

Key limitations to consider

This is a solo microwave, so it won’t replace an oven for baking, browning, or grilling. If you mainly want “proper cooking” beyond reheating and defrosting, you may find it doesn’t go far enough.

Also, while the controls are described as friendly (including for older users), ease of use varies from person to person. If you’re sensitive to how buttons feel or how menus display, it’s worth checking the control style in your own context before committing.

And although the listing states features like defrost that aim to avoid overheating, microwave performance ultimately still depends on food type, starting temperature, and how evenly you arrange items inside.

Who it’s for (and who should skip it)

It makes sense if you want a compact 20L microwave that’s easy to operate, with enough flexibility to adjust cooking via 11 power levels and time-based control.

You’ll likely get the most from it if your routine is centred on things like reheating meals, warming drinks, cooking common frozen items, and using quick express timings when you’re short on time.

It may not suit you if you regularly need oven-like cooking functions, or if your cooking style depends heavily on specialised modes beyond what a compact solo microwave can offer.

Is it worth it?

This Toshiba Black Mirror is a solid “day-to-day” microwave pick on the basis of its 800W, 20L capacity, and the combination of 11 power levels, express time selection, auto menus, and defrost. If you prioritise speed plus enough control to avoid overcooking, it fits the bill.

However, if you’re buying for anything beyond reheating, defrosting and basic microwave cooking, you may find a solo unit stays in the mid-range of what a microwave can do.
