It's really great this device you can buy food on sale or in promotional and evacuating they keep longer, examples, I go to buy organic farm cheese, now I go once every 2 months = fuel economy I took 2 kg I share 6 for evacuating, I have a vegetable garden, I cook a full pot of red beets (1 hour) and I share them in bags under = empty cooking economy, I peel several salads both = water saving etc ... So I'll buy two more for christmas my daughters.
