... Well. It's annoying, it would be plugged everything in, extracts the air and dragged it down to the basement ... after 2 days you look random from the bag and have filled with miefiger cellar air ... grrr ... This was not the purpose of the exercise. I admit that I have the bag of course a bit difficult and it may well be that you now and then on the coated PVC staircase "very softly sprung" is what has probably already caused the smallest little hole. I use it now for things that do not need to be kept airtight.
