there could b many reasons. Most people might think that the oven is a defect. There is also another reason, her power supply has problem. May b her wiring got problem or etc? Fotile's technicians specialize with their products and they are not trained wiremen, so they could not identify if there is a power supply issue. We do not know the exact story and so far there is only one complain, i sold many units to forumers and none complain about it. I googled and only found one bad comment about fotile which is the lady complaining bout the oven but there are heaps of good comments in LYN and also other forums.

**Updated
Just checked on her profile and noticed that she joined on 11 June and last seen on 11 June, total Post = 1. Which means she purposely create an account just to post that comment. So, dont think it is a reliable comment as it might be some competitor's tactic to defame other brands and to push their products.

Furthermore, Fotile's oven warranty is 1 year only, imagine if u were in her shoes, would you pay to repair the oven after the warranty period since it break down so often (she said break down 5 times in 2 years, which means she paid to fix it minimum once after the warranty period) ? I will definitely buy a new one as usually it would be costly to repair and also i will feel it might break down again if I fix it since it break down so many times after repairing. If it only break down once then i will definitely get it fixed.
If u wan to be assured that Fotile is good, you will just need to PM some of those who are using FOTILE in LYN forum
EG: PM those people in my spoiler.

Btw, could u upload some photos of ur receipt + the complaint report as evidence, so that i could get ur details and lodge a report for u? I will try my best to help u to rectify the matter though u did not buy from me.
