Have the toaster a few times to heat without content. Here I noticed that in some areas no filament glows. But in other areas, but the heating wires extremely glowed! Ok, in the price range you can expect a little more quality: Spare requested. Here then was a real exchange unit! Without protective packaging! Cardboard not even glued! Carton is apparently already gone some way ....... Post Replacement unit saw visually good, but the heating wires were the absolute joke! Even fewer areas were glowing, but were some nice heating wires far ahead! Ok, again causing an exchange. Amazon also provides information on the packaging. Replacement I packed immediately after the optical control! Contaminations in the toaster where the toast is on it, are surely completely unacceptable! Hab times scratched with a fingernail is not going off!
