1) Poor performance: Even normal toast must be gestoastet starch 4 to accept any color. Mischbrot can get brown rarely below level 6. Warm it is otherwise as well, but not crisp. He also seems to me (purely subjective) very slow toasting, I feel, even at level 4 it takes forever.
2) Poor mechanics: the platform on which rest the bread is very hakelig. In the high jump to toast the end thin slices falling down regularly and jammed between the platform and the side walls. One must then using a knife or a fork better try to get the wheels freely.
3) Wobbly Brötchenaufsatz: More is nothing more to say - it's just shaky and does not look very strong.
Conclusion: Actually, only worth one point, but because of the send appearance (and if you buy just because of appearance, this is important) I give two points.
