Good, but could definitely be better.
3/5
Seeking a replacement for my much-missed previous combination oven which sadly expired in a cloud of noxious smoke a few weeks ago after 20 years of sterling service, I sought advice from various online reviewers and eventually chose the Panasonic NN-CT56JBBPQ, believing it to be almost without flaw. It would seem that I was mistaken.
Setting the time requires holding the "1 hour" button while the hours tick up at a seemingly random rate, and if held just one pulse too long, it is impossible to wind the clock backwards — one has to start all over again. The exercise then has to be repeated with the "1 minute" button, or with a combination of the "10 minutes" and "1 minute" buttons. Then, if one notices that the time is slightly wrong, there is no possibility to adjust it — it has to be set from scratch all over again.
The six power levels are (a) glossed by description rather than by power or by percentage, and are presented in what I regard as an illogical order : "high" (100%) / "defrost" (27%) / "medium" (60%)/ "low" (44%) / "simmer" (30%) / "warm" (10%), with "defrost" (27%) interpolated between "high" (100%) and "medium" (60%). Why ? And why select these arbitrary values, rather than allowing the far more obvious and intuitive sequence 100% / 90% ... 50% ... 20% / 10% ?
From an ergonomic point of view, I am not impressed by the touch-sensitive controls — I far preferred the more reliable conventional push buttons (and dial) of my previous machine. The touch-sensitive controls seem more than a little arbitrary in the way that they respond to user pressure. And why is the interior light not a LED ? If the door is left open, the oven gets appreciably warm from the heat from the lamp; this seems a great waste of energy.
In summary, I preferred my old previous machine — the Panasonic will do the job, but when it shuffles off this mortal coil I shall replace it with a model with conventional controls, a dial, and 10 power settings in monotonic decreasing sequence.
