I bought this oven over 1 year back. I found it working well initially. Over time though I found that the temperature did not increase to what I wanted it to reach - I set it at the highest, but it did not go over 180Deg C. I managed by inserting the cookie sheet rack at the top effectively reducing the size of the oven. I reported to the Faber and they sent a technician who was trained to handle...chimneys!
He probably did not know anything about temperature - he said that it is heating and left!It should be a simple recalibration I think - but need the correct technician.
Will I suggest this to another person - definitely a big No! Faber has very poor service for these products and they should stop selling it. The manual I received is a very poor translation - does not make any sense.
