I bought this because of the ceramic lining. It is replacing a previous microwave in which the lining had deteriorated so am hoping that won't happen with this. I have a couple of quibbles with it. Main one is that you can only time items in 30 second bursts, I am used to having a 10 second function which I really miss. The other problem is the user manual. The one supplied was inadequate, then I found one online. It's descriptions are really useless. Tried to use the eco function, but have no idea of it has worked as the instructions seem incomplete.
