Q & As

Panasonic NN-ST452W Microwave Oven, White 4.2 5 34 34
Good Microwave It is a good microwave, has plenty of room inside, power is good for cooking and warming. It would be better if inside was painted white. 16 December 2014
Great Product We chose this product as we have always been very satisfied with Panasonic Microwaves. We trust that this microwave will last as long as the other one. We used the click & collect service which was fast and highly to be praised for its convenience. 16 December 2014
Microwave OK but display problems I was replacing the AA554 combination model that had lasted quite a few years.Had this microwave-only model for two months. During that time, although the microwave functionality was good, it lost the clock display many times, requiring re-input of the time. It also displayed random error messages, requiring switch off and on at the mains. Contacted the fabled John Lewis service centre and can confirm that it is all that has been reported. A replacement or refund were offered but I asked whether I could upgrade to the next higher model. This request was accepted and I have now received the 552 combination model for a small increase in cost. Super service and the 552 model is less 'tinny', probably because of the additional equipment inside the microwave. 15 December 2014
QUICK AND EASY We've had this microwave for just over four weeks, but seems longer. It's easy to use and cooks the food quickly and evenly. We've not encountered any of the problems some other reviewers have experienced, so we're very pleased with our purchase and happy to recommend it 30 September 2014
Panasonic NN ST452W Bought a number of these over the years in various formats. Generally last 8 years or so. My recent NN ST452W with the Inverter has been a pain. The food takes longer to heat/cook and my recent one lasted around 18 months, Inverter failed. Need replacement now and reluctant to buy another, especially the Inverter type. Combo's look a waste of time, due to the cleaning process if food ends up on the grill. Much easier just to wipe inside if you have any problems. 30 September 2014
A good well designed microwave Our previous Panasonic microwave lasted 15years. If this one does as well we will be very pleased. It looks good and does all that we require. 02 September 2014
Panasonic NN-ST452W Microwave Oven, White Simple to set up and use..does what it says on the box!! 22 July 2014
Bring back 10-power-level microwaves with better technology It seems impossible to find a microwave in the UK to replace the excellent microwaves of a decade or two ago - the kind that had 10 power levels so you could choose exactly which power to use; the kind that had a good and sensible delay start function that still showed the time when delay-start was on; the kind that gave a loud series of beeps that you could hear in another room; the kind that did not have a noisy fan (like this microwave) that drowned the sound of the finished-cooking-beeps; the kind that defrosted (power level 4) in half the time and with better results than this microwave; the kind that allowed the user to be boss. I have cooked with microwaves for almost thirty years. I would not recommend this particular microwave. It has a very noisy fan, the end-of-cooking-time beeps are too quiet, the delay-timer is not user-friendly and stops the display of the clock/time, the defrost function is poor. It only has 5 power levels but the spec does not tell you their output. And it is "tinny". Very disappointing, especially for the price. If anyone knows where I get get a good old-fashioned, large, 10-power-level microwave, simple but better than today's technology, I would love to know. I could get several different 10-power-level models in Australia, and probably the USA as well. 05 July 2014
