The only complaint would be the oven itself is that only 4 of the 5 grooves to ask the grids are used, one of five being interrupted by the bulge of the fan on the right. It's a shame for some gratins.
The manual is unfortunately needy. Can be downloaded on the website of SEB a recipe book in PDF format. It helps a little to understand what cooking method, what temperature and how grid height choose, but we would like more help on it, or on the website of SEB or in the user manual.
