curious phenomenon

Received this morning, at noon ..... that use the classic (chipos, sausages ...). The bbq works wonders, the advice of the first use of usage.Le curious side of the case lies in the that inside, blush resistance in 2mn, while outside, they remain hopelessly gray, which would suggest that the heating is minimal .... there is nothing (the device however, was plugged into the same outlet, even extending, the same conditions of use ..... except the fact that we were out) Fun? is this pas.A than that, it is easy to clean, but do not have thermostat, or ignition button (actually connecting the office.), and for those who can, I recommend to keep the carton packaging ...... for winter storage.
Good barbecue.
