Q & As

Rated 4.4 out of 5 by 74 reviewers.
Rated 4 out of 5 by Desperate without microwave I decided to buy another panasonic but first one delivered had mark on door which must have been obviously at the factory, so had to get another one, this one has mark on glass plate but not so obvious. I hope this one lasts longer than previously one as I just found receipt and realised it was only 3 years old. The door opener broke and maybe could have been repaired but was probably cheaper to buy a new one, anyway good service from JohnLewis as usual. 01 July 2015
Rated 5 out of 5 by Good product Easy to use and large enough for dinner plates when reheating meals. 30 June 2015
Rated 5 out of 5 by Excellent Bought to replace our old Panasonic microwave (which has seen good service for almost 20 years). Hope this one lasts as long 24 June 2015
Rated 5 out of 5 by very good microwave I am learning to use it but have not had the chance to find all that it can do. It has more functions than my old version 16 June 2015
Rated 5 out of 5 by Great Microwave. As usual Panasonic have produced a great product. Looks good. Very easy to use. Cooks very well. In our opinion we would never buy any other brand. As they are so reliable. Very very pleased. 02 June 2015
Rated 4 out of 5 by Decent product My parents bought this as their first microwave, and so far they haven't had any issues with it, so I guess it's easy to use. It's massive - takes up most of the counter space, but you can fit large bowls in so good if you're heating up large amounts. I particularly enjoy the 'chaos defrost' and 'turbo reheat' buttons - never used them, but they sound exciting! My parents have experimented a bit with the preset buttons, and they seem to do the job, so overall a decent buy. 24 May 2015
Rated 1 out of 5 by Wouldn't even give this a 1 star This is an appalling, shoddy piece of equipment. The first one I bought didn't last longer than a year before it started emitting large flashes and could not be used. Like an idiot I replaced it with the same model and this time it didn't last the year before it broke down exactly the same as the first one. John Lewis were brilliant and organised a repair, but as the waiting time was too long they replaced it with a new one. This has has not lasted beyond a few months and has today broken down with exactly the same fault. This will need me to return again to John Lewis to deal with it. As this microwave was a replacement for the first one I didn't receive any paper work with it, which will mean more aggravation and time to get this matter rectified. In my opinion this product obviously has serious design/manufacturing defects. I have always bought Panasonic microwaves and all previous models lasted me for years before I needed to replace them. 10 May 2015
Rated 1 out of 5 by OKwhilst it worked but cannot recommend Bought this Panasonic microwave to replace our old Panasonic 900 watt "inverter" model purchased in 2005. Worked fine for about four weeks normal use then suddenly stopped working - no power, no light, nothing! Could have been a one-off faulty component, but when John Lewis offered a replacement we decided not to risk another Panasonic, and chose instead a Bosch microwave, paying an additional £20. Will now find out if the Panasonic "inverter" technology really does make a difference. I have my doubts. 24 March 2015
