cold plate

We have purchased the product in the short term in the media market for Christmas to support existing among our neighbors simple raclette because we had "to supply" so many people. The device itself looks really good, other than the food on the plate above that after 1 hour was still not brown despite the thermostat is fully open. The other side of the Spree had already launched the 3rd season with the simple device! Because the mockery was of course great. I have the impression that the thermostat switches off the heating for too long, because in the short term the flesh even sizzling, but then was back for several minutes rest in the upper story (the hysteresis is too wide).
We have brought this Raclette back. I curious to look like other reviews, because theoretically our device may have been defective Yes simply ..........
