If i would need this container for longer storage than a week this product would not work for me

On first try the vacuum did not hold for more than a couple of days

After several months the seal has worn down and it gets loose after a few hours

Container looks very nice but vacuum only hold for 5 days and the little indicator rubber rises more than half way after 5 days i can lightly pull the top cover and it comes right off with not much suction left i don’t think vacuum will hold tight for 30 days or even near that it still work for my situation since i stored beans and open to get the beans daily to grind than reseal with the provided pump for people who want to store anything longer i’m not sure if it will work
