Q & As


Panasonic NN-ST452W Microwave Oven, White 4.4 5 22 22
Could do better After reading lots of reviews we opted for this model. Very disappointed and packed up after 10 months. Off to John Lewis we go........Not the best microwave. Doesn't do what it says on the tin. Defrosting items by weight is very poor and in my experience didn't do the job. Worth the £££. No. There must be better out there. 25 February 2014
Does what it says It was bought to replace an elderly model with similar properties. Even though I've not tried all the features, what I have used works well and made me realise how inefficient my old one had become. The instruction book is easy to follow and the keypad easy to use. Yes, I'd recommend it on my experience so far. 13 February 2014
Super Microwave Really good value for a large, simple to use microwave. It has stylish good looks and holds large plates and bowls easily. 12 February 2014
Easy to use We bought this as a replacement for a similar Panasonic microwave which had given us years of good service. This was the updated version of our old one. Researched the market looking for a replacement but could not find one offering such a spacious oven with all the features we wanted in a stand alone Microwave except for this one. We like the look of the product but more importantly it is easy use and cleaning of the inside is also easy. Our older model had a stainless steel inside but this new updated one is a hard grey surface but as it has a light inside this is not a problem. The operation is by pressing the function button to select the programme ie high, defrost, medium etc and then setting the time. There are also auto programmes for cooking and defrosting. The top of the microwave does not have any vents which is handy, the vents are on the left hand side. Would highly recommend this microwave for anyone wanting a stand alone oven that will take a large dinner plate or a large high rice cooker for example. 05 February 2014
Nearly Great NN-SD271 First class service from John Lewis click and collect. Microwave also very good but 2 caveats. One: The clock has a very limited viewing angle and when viewed at worktop level and from less than a couple of feet, the digits disappear. Two This is a current model but Panasonic says it is unable to supply the fitting kit, it is out of stock and they are unable to give a date if or when it will ever be available. 04 February 2014
Panasonic NN-ST452W continues to be an excellent product Our 10 yr old similar oven gave very good service. I looked around for a replacement and finally decided to stay with Panasonic and am very glad I did - after 1 month. Easy to use; has the functions we need to use every day plus a few short-cuts. We are pleased with another quality product, very promptly delivered by JLewis. 31 December 2013
Could be better This Panasonic was bought to replace an older and better model. We tried more expensive ones, but they weren't so good so went for this model (after many failed attempts with other Panasonic models which were all replaced#. This one, for the price, is ok. Just seems Panasonic microwaves are not built the way they were 6-7 years ago. This one is quieter than some of the other newer models, has all the functionality that you could want in terms of cooking, heating, defrost etc. Done by weight too. It's large inside, which was important to us. However, the door keeps getting stuck and heavy so needs to be banged shut. The plastic on the keys outside wears away and gets bubbly/torn after just a few months. We have had this same model replaced 3 times in the year we've had it as the first machine just stopped working on us, twice! The second the digital display wasn't working properly #though that was the only one where the door didn't stick). Now this one. This new replacement is only a few months old, so we'll see how well it lasts. 22 December 2013
Brilliant product This microwave is brilliant - it has sensors to cook your fresh or frozen veg!!! Fantastic. Some people have commented on the noise - we have it in our utility room so that doesn't bother us - also I'm not sure it is 'loud' . The capacity is great for large plates. just completely happy with it. 18 December 2013
