This little beauty is rapidly building a following amongst many of the UK's Microwaving hobbyists (or 'Wavers' as we like to be called). Known affectionately as the "Double N" the NNA554W is quite possibly the first 'wave in the UK to feature Neoprene feet. It has long been posited that the traditional rubber compounds are both resonantly-inefficient, and liable to become unstable if pushing the electromagnetic wavelength above the usual microwave range, in to the UHF domain, as is used by some American television channels. (This could happen if cooking walnuts, and forgetting to remove the foil packaging, for instance.) As R.Tusk concluded in the insightful "Quantum Consequences of HF Shift" (Tweedy Press), operating a laptop next to a frequency-instable microwave can lead to data-loss, and in extreme circumstances, hair-loss. (Low-intensity microwave radiation is used in Wi-Fi.) Thanks to the Double N, these worries are a thing of the past.
Microwave energy is manifested with Magnetron and Klystron tubes, and with solid state diodes such as IMPATT and Gunn devices. But as we say at NFOM-FOM (National Federation Of Microwave-Frequency Oven Machines), "A Klystron and Gunn does not a good Quiche make!" What you want to know is "How does it cook!?" Well, generally, or medium, or rare. Or simply in a manner likely to defrost. Let's not get pedantic, it's a 'wave, ergo, it cooks. This is not a general purpose machine, it's aimed squarely at the food preparation market; if you want something more flexible, then I would try something like a kettle (Go Kenwood!), or the new Multi-Mate. All in all, I would recommend this on its feet alone; the cooking facility compounds its buy-ability, and if you forget which one you're supposed to buy when you get to the shop, remember this: "The '54 Double-U, Won't ever trouble you!"
