Microwaves: Compare features & prices Panasonic NN-CF778S review http://www.which.co.uk/home-and-garden/kitchen/reviews/microwaves/panasonic-nn-cf778s/review/

We bought this, as per many others, based on Which review and the looks. We had a Panasonic prior to this which was too small and was about 10 years old but worked well. Positives: The lack of turntable is brilliant. It allows for awkward items to fit in and work. The drop down door is brilliant (so long as you don't want to mount the thing high up). Negatives: Everything else. It cooks very unevenly, defrosts randomly (in manual) and changes what it is going to do on a daily basis. If I didn't know any better, I would say it has a 'pot luck' setting attached to everything you do. Some days it will warm a mug of tea in 40s, other days (same mug/temp) will do the sum total of basically nothing in the same period. We have had it repaired once (didn't make any difference that we could tell) and it is now out of warranty so we are stuffed. As one of the previous commenters said - it also requires multiple presses/twiddles just to get the thing going. If it wasn't for the fact that all our previous microwaves were Panasonic and great, I would be seriously put of this brand. I am also slightly concerned that Which rate it so well. Whilst I think they get most things right, the issue of longevity is something I would actively point out as a major failing with all their testing (granted - this is somewhat hard to do but there must be ways of speeding up the process to give an approximation). This is also true of the Which best buy BBQ that I bought and kealed over the minute it got cold but that's another story and afraid that is not the only product! We are now going for the NN-ST479S - Which best buy No.1 - 80% - and hope (as a microwave only) it does warming and defrosting well as that is all we use it for.

Bought this based on loads of positive reviews. However shortly after buying, our mains rcd started tripping out. The house is 8 years old & it had never done this before. We'd go a day or two or even up to 8-9 days between incidents, but then other times it would trip out 10 times a day! We've had every socket in our house off the wall, an electrician out evenings and weekends.......expensive habit.......& it turns out the culprit is our shiny new combi microwave| John Lewis were brilliant, as usual, & took the thing back without any issue, but we're still left with a hefty electrician bill. I've now found a few other reviews saying this micro trips their rcd, so if you go for this model be aware of potential issue. I assumed that an appliance would only trip the rcd when used. It doesn't. In our case it only had to be plugged in, not on, to cause the problem. Its been gone 3 weeks now & no further rcd problems - so no question that this micro was the culprit I'm afraid.

The NN-CF778S has been working really well for me for over a year so far. I like the fact that the door drops down, rather than opens sideways, as it makes loading and unloading easier. But, one of my favourite features is the fact that you can change the microwave power on the fly, just like you can turn a hob down to a simmer once something is boiling. The use of an inverter means that you get properly adjustable power, rather than full power for 30 seconds followed by no power for 30 seconds.The fan oven isn't up to the same standard as a good full sized fan oven, as it seems to use the grill elements to provide the heat. I tend to find this cooks the top of food a little faster than I want.

very poor, used twice then when attempting to use for the 3rd time, powered on then opened the door, load bang and a flash of light from the inside with such force it tripped the main power switch in the whole house, before it was even in use. Panasonic insisted on an inspection which turned up a faulty switch with the door casing there are 3 switches one was faulty hence the explosion when I opened the door. Would not touch another one of these with a barge pole. I suggest which re-evaluates this oven. I had to insist on a refund as Panasonic wanted to do a repair. Stood my ground on safety grounds as I could have been injured and managed to get a refund from Dixons.

Purchased from Kitchen Aid at the end of June 2010. Kitchen Aid we now know is part of the comet group Little used until September. Would not maintain conventional cooking temperature, and only heating one side. Then discovered Panasonic had sold the warrenty to Comet. It took the comet group from September to early December to repair it. Attempted to use it,sparks from the right hand side,and a smell of burning. Kitchen Aid policy to attempt another repair,if not replacement. Eventually after repeated phone calls, refunded in full. I would not buy another Panasonic. The casing was too hot to touch,and we were informed by Comet engineers that the cooking temperatures had a manufactures tolerance of +/- 10c Degrees. The conventional oven whilst set at 220, gave an internal temp, of 165c, on one side the other side food was raw. We bought it as a Which best buy. I think Which should re test this item! We have various Meile products which are excellent, and have bought a Meile micro wave/grill. It does not appear on the Wich trials. Why

I bought this model to replace a previous Panasonic Combination microwave which I had had for over 20 years. This one only lasted 16 months!! I am NOT pleased! I have replaced it with another make.
