Like any Toaster nowadays so well this works on the famous pop-up principle. This really means nothing other than that the slices of bread are toasted evenly brown on both sides. Only there is not just the way as usual two, but immediately and four slices of bread to toast in a roasting process here at Severin AT 2509. The device itself is very well insulated and the slices of bread rise even after the roasting process sufficiently far enough from the toasting slots out, so you need have no concern fingers getting burned. The Severin AT 2509 does its job quite excellent. It does not matter if you use frozen or fresh toast. The natural tanning results are dependent on the selected degree of browning. In both cases, whether fresh or frozen, I can toast the results consistently evaluate with good. On average, the device takes approximately one minute to toasting with four slices. The integrated roll-Röstauflage can also be baking this in a very short time if needed. In this case, I was fully satisfied with the results delivered me from the device. Highly recommended is the warm-up function in this toaster. This already can be toasted slices again bring "in form", without these being again browned. A feature not offered by any toaster so readily. Positive I evaluate also the removable crumb tray, the cord storage facility and contributing to the stability of the device non-slip feet. Even the look of the AT 2509 is an absolute "eye-catcher". And if you should opt for the purchase of this device, then this Severin automatic toaster could secure the future also decorate their breakfast table. Absolute buy recommendation!
