Space Bag Review

I read some other people's complaints about Space Bags and also saw rave reviews. I read online that they had some new and improved material they were using for the bags. So many stores carry it (Target, Bed Bath & Beyond, Costco, Wal Mart, Linens N Things, QVC, HSN...etc.) I thought maybe it was user error or that the product improved. With that in mind, I went to linens n things to purchase it so I could easily return it if they didn't work. I was so careful and treated the bag gingerly. I put the clothes in there, sucked out the air and was amazed at how well it worked. I then put it in the closet and began to load up the next one. Within 5 minutes I walked back to the closet to get more clothes and could see that the bag had already began filling with air again. All these reviews are right! I honestly cannot believe that all these stores continue to carry them! Very disappointing that not only do they not work but that so many retailers who consumers trust would carry them.
