I am surprised that these are being discontinued. I tried Lakeland vacuum jars, which lost their vacuum in a couple of days. I had tried vacuum boxes. Ditto. These keep their vacuum for at least a month - probably 2 or 3. I particularly like them for raw meat aqnd salmon which I smoke, which I put in a thin bag first, to keep this clean. It stays in excellent condition in the freezer. Reprieve the airlock bags!
