I ordered this machine in late August with the dream of finally realize myself all my preparations. The first yogurt were perfect, the bread. I have not tried the jam or cottage cheese. From the 3rd use, the texture of yogurt has changed as I have not changed anything to the ingredients or the recipe. They are now still liquids despite my 12 hours of programming and ferments. As for the cake or bread dough, it no longer swells once on 5, recipe and ingredients identical too. And to top it all, the lid is firmer. We are obliged to maintain with tape !! I wanted to return it but my 30 days had passed. It remains for me to contact the manufacturer but I think it really bothers me a lot because I thought I had found the perfect machine. In summary, very sensitive machines. It does not work well. You will be thrilled at first, disappointed later. I absolutely do not recommend.
