Update: Having received several packages with a manufacturing defect which caused many to leak, I was sent a replacement asap and the damaged ones were sent back to them for inspection and repair. I appreciate that they really care about fixing bugs on their side so that future customers don't have any problems. I'm not sure where the leaks are coming from, but I've never had this problem with other vacuum bags. Almost all seem to have a slight leak that is noticeable after 24 hours or less. I've vacuum packed a bunch of rice, beans, beef, pork, etc. and more than half of them lost their seal there.
