We shit-canned our 'foodsaver' brand item, and upgraded to a (similar cost) Cabela's machine that is ELEVENTY times better. It works better, is easier to clean, is faster, AND the best part is there is SO MUCH less 'thrown away' bag material.
I'm sure foodsaver (company) purchases a new airport a day with all the excess 'bag' material designed into their process. The biggest difference that changing brands did for us, is nearly doubled our 'bag waste' problem.
Some of ya'll will get that. And the rest will be telling me/us to 'go be poor somewhere else', I know.
