Nothing to say about this, I own for a year. Compatible with the yogurt maker Seb (ref. 887201), these pots are glass of very good quality, robust, thick. The lids are sealed tight and fit ideally on pots, yogurt are well protected and food hygiene is fully respected. And no risk that the pot is opened, for example in the snack bag. When I bought my yogurt, I did not hesitate to take this game pots simultaneously. This makes it possible to rotate and always have yogurt in the fridge. I would add that everything goes in the dishwasher, which is an important asset !!! In short, I recommend without reservation.
