When I opened up a bag to stuff it with blankets, the "blue cheap zipper" had already ripped the bag.  There goes a bag! I then opened the 2nd bag and stuffed it with blankets and sucked the air out with vacuum cleaner.  Did the same for the 3rd bag.  An hour later, not kidding, the air was back in there!!  They are only last for about an hour and then the air comes back!  What a rip off!  Just go and buy yourself some garbage bags and stuff them with the blankets.  You might be saving about $20.00!!

Dont buy them!
