I will completely agree with the previous speakers, products like this and others similar with high prices aim to offer some special service that, however, after a short use, one realizes that they are just empty words. In the meantime, it cries for the money it wasted, before throwing it in the trash.. Advice: never throw away the empty coffee jar, it does exactly the same job and it is already included in the price of the product, i.e. for free!!!

Very expensive without an obvious reason. The construction is very simple and does not differ in any way from the simple airtight stainless steel containers that cost 5 euros. I highly doubt if this valve it has actually any effect on the freshness of the coffee. Also, the indications for the date on the lid are with stickers that have not been stuck well and overall it is very sloppy work.
