I hesitated to buy this machine because different cover defective comments. That's why I waited 8 months to give my opinion. I use this machine several times a week to make 4 batches of yogurt (regular and drink in glass jars and plastic water bottles) and two loaves and buns 2 a week. From time to time I also do cooking rice and cottage cheese. I have not tested jam. My opinion is very positive for this device works perfectly, my yogurt are perfectly successful (I use the Alsa ferments) and my bread and buns. No lid closing worries for now, maybe they have settled the problem? This device has replaced my yogurt, cheese and especially my my bread machine that made the soul a little too fast! The round tank made me hesitate also because my previous machine had a bread bowl XXL length and finally the use I find that this is not a problem at all. For yoghurt I do not use the Lagrange pots which I find too big but those of Seb brand, which allows me to go 12 jars per batch. In short I am delighted with my purchase which for me is a real gain of space in my kitchen and saw that my use is economical and healthier for my family.
