Air is quickly there.

I have two bags filled and the next day was in a little air in it again, even though everything was tightly closed. The fact that the price no miracles can be expected, so I was expecting, but that it just holds a day, but then very little. The other is still tight, but is also only a couple of days in use. The rest I have, as I said, not yet used. These bags are very thin. A false grip and has a hole. For the cheap price I give then still 3 stars. Just like that.
