Q & As

Rated 4.3 out of 5 by 184 reviewers.
Rated 5 out of 5 by ANOTHER PANASONIC MICRO- OVEN My first Panasonic lasted 25 years, this new one seems as well made and has amazing talents. Worth the extra cost over the alternatives, I believe. 09 December 2015
Rated 1 out of 5 by Yet another one gone wrong I am returning the microwave oven tomorrow as we have had for a whole 10 days use but, it has now stopped working after making an alarming noise. I should add this is the third one in 6 years all the same model number. 01 December 2015
Rated 5 out of 5 by Lives up to Which? review I read some negative reviews which made me umm and ahh about buying this microwave but it does exactly what it says on the tin. I like the controls - quite clear and simple - easy to set up. Its capacity is bigger than my broken microwave but externally it seems same size. I find that the fan does continue after the cooking is finished and I suppose that could give the impression still cooking when door opened (but it isn't). Love, love the defrosting facility - works a dream and much better like 100% than my old one which used to 'cook' partially. This one does not do this. 25 November 2015
Rated 5 out of 5 by Excellent microwave oven There were two main reasons why we chose this model. First, our previous microwave oven was a Panasonic, which had served us well for several years. Second, it is a Which best buy. Delivery by Royal Mail was prompt, so we were without a microwave for only a few days. Thoroughly recommended. 24 November 2015
Rated 4 out of 5 Indispensable ! Not irreplaceable because I just did that, but a microwave with these features -- timer with great accuracy, preset programmes, and so easy to clean had become so integrated into my life in the kitchen that it HAD to be replaced as quickly as possible. 24 November 2015
Rated 4 out of 5 by Would find it difficult without this product Our new Panasonic microwave is very easy to use being similar to our previous one. 24 November 2015
Rated 5 out of 5 by Great value My old microwave just stopped working so I needed one right away so of I went to John Lewis who had an array of microwaves to suit every pocket I chose this one and have used it two of three times a day I love it it does exactly what it says on the box brilliant 24 November 2015
Rated 5 out of 5 by Good piece of kit Excellent microwave. Slightly larger than I realised but will take all my cookware. Very short cable, had to be extended. 24 November 2015
