Tried several and none worked
I put some blankets in one of the jumbo bags and within HOURS some of the air was back into the bag. The plastic material these are made out of is much too thin. I had ordered a kit that contained several bags in various sizes. I hoped that I just received a faulty bag. But unfortunately, with each bag I had the same problem of air leaking back in. I'm thankful that I didn't just put my items in, suck out the air and then forget about them, because my items would have been ruined. I wasmreally disappointed - I love the idea and wish I could find a brand that actually does what it promises. I use a FoodSaver brand vacuum sealer for my food and am thrilled with how it protects, so I know the technology exists for this concept. The problem seemed to be with the thickness and type of material the bags were made out of. They seemed to be too thin. On the plus side, they were easy to use, easy to fill and easy to suck the air out of with a vacuum hose. The variety of sizes of the bags is great as well. Maybe I'll try them again some day...
