Heater much too strong

I thought of a manufacturing defect but given all the other reviews stating the same thing I tell myself that it is general.
The first use went very well and we were happy.
As against the second smoke detector triggering placed in the hallway while we were in the dining room.
It was not was well aware that we were in a cloud of smoke.
Ok, aerate.
Only the pancakes stick to background, cook very quickly, and index that does not deceive, plastic spatulas our raclette melt!
The big one we change takes spatula for pancakes and background too!
The plastic is not very good, we will use it more.
