The warm-up takes, as indicated in the instructions about 8 min., So just 8 min. Switch on before use and the device is available. I confirm all the other positive aspects of the other reviews, but: If you want to grill sausages but it is mühseelig because it is not a BBQ in this device defacto (where grilled by thermal radiation), but an electric frying pan, where mainly "grilled" by contact of grilling and frying surface is. This makes it difficult to get the heat z. B. in Thuringian sausages, because the contact surface of the sausages is very low and therefore the heat is poorly transported by the device in the sausage (points of contact for fast black). As you turn then to tan the sausages on the other side, where they touch the "Grill". On the outside and the inside of the bend, the sausages remain white, as the heat radiation of a ignition coil, or charcoal is missing. In stronger winds, with wind protection, it gets really problematic with sausages. When the sausage is rotated all the time and turns and holds a Grillzange it takes min. 20 min. Until they are browned reasonably evenly. Not a pleasant "Grillerei". The same goes for vegetables pepper strips z. B.. At the intersections of fast black and normally would, since the heat due to the minimal tangential contact points can not be abgführt of the vegetables do not. In a frying pan heat could be forwarded with oil on the vegetables, which is not possible with this device, since the oil runs out. For steaks, chicken breasts and turkey kebabs (are soft and can be pressed flat), this electric skillet perfect.
