We have had the Cafe range for three week and very happy with all aspects of the product except for the surface grates. The material of the grates is very likely to scratch the stainless steel panel because there are no rubber bumpers on the grates. Unless you replace the grates extremely carefully after cleaning it is very easy to scratch the stainless. We contacted Cafe Customer Relations, but they were unable to find a solution.
