Panasonic NN-ST479S Sensor Microwave Oven, Stainless Steel

Product information

The family size Panasonic NN-ST479S microwave oven, in stainless steel, features 15 programmes, 8 with an automatic sensor so there's no need to enter the weight.

The NN-ST479S also has built-in inverter technology that provides more even and constant cooking. This technology also reduces the weight of ovens, making for easier cleaning.

This model comes with auto weight reheat, auto weight cook, turbo reheat, chaos defrost, all of which take the guesswork out of timing. Includes jog control and distinctive double pop-out control panel.

Please note: for proper operation, the oven must have sufficient air flow i.e. 5cm at one side, the other being open; 15cm clear over the top; 10cm at the rear.

Rated 4 out of 5 by An attractively designed functional addition to my kitchen Adjusting to increased power -most frozen meal/recipe instructions stop at 850w-acheived by trial and error! but once mastered excellent results. 22 April 2016
Rated 4 out of 5 by Loud and Quiet Yes the title seems like an oxymoron but I refer to the fan which is unnecessarily loud and the ‘pinger’ which is not as loud as our previous machines. The fact that the ‘alarm’ sounds but the fan continues after cooking is complete takes a bit of getting used to. Pros • Sensor cook is good • ‘Inverter’ technology is a massive plus bringing sanity to these machines • Stainless steel yes and no • Inside great, outside NO • Very easy to clean the inside Cons • I personally do not like the display • The machine gets really hot on the outer casing, even though the fan goes on and on • I don’t like the buttons, for those visually impaired a nightmare This machine, despite the above does its job well so if your hearing is ok and you can get used to the machine making a noise even though it has finished cooking then yes buy it. 20 April 2016
Rated 1 out of 5 by Disappointing purchase We bought this model because we have had Panasonics in the past and been very happy with them. However, we were very disappointed when we got it home, away from the bright lights of the shop because the control buttons are virtually impossible to read without a very good light and a magnifying glass. The time settings are far too tiny to read easily. The first model we purchased broke down after only 18 months or so, but John Lewis were fantastic in terms of a speedy, no quibble replacement. However, the second one also broke down, with the same problem (simply stopped working) after only a few months, so we got a refund and bought a different make. Maybe this was a faulty batch, but wouldn't purchase this model again. 12 April 2016
Rated 5 out of 5 by Typical Panasonic quality We always had Panasonic microwaves but opted for a different product brand which didn't last very long. We have reverted back to reliable Panasonic! Easy to use, looks good and a sturdy product. 12 April 2016
