Do those as seen on tv space bags work as advertised?”
I bought a ton of the space bags, but not all held their suction, dispite my best efforts. I switched to the ziploc xl-xxl big bags that are available at most any store and just suck some air out. They seem to hold the seal better. I guess to sum it up, the space bags are okay, but the ziplocs are cheaper and seem to hold the seal better.
