The raclette grill is properly once so started before the first benefit, as described in the instructions. The first (and only) use to Silvester the process was completely oiled grill plate and the device was relatively short heated to a high level. During most of the thermostat was set at a medium temperature. After cooling of the device and the panel we have this just soaked in soapy water and treated with soft soft cloth. And broke up in several places the coating.
The unit operates otherwise perfect, but the grill plate coating is anything but high quality. As another Amazon customer reports of exactly the same problems at the moment, I suspect that a lack of quality of the batch of barbecue plates could be.
Conclusion: device on Amazon returned, reimbursed the purchase price without any problems.
