DO NOT get the Vac-Vida VS301! I bought one through Amazon in January 2020 because supposedly the company would stand behind their product. That’s a lie! Mine started giving me trouble in Dec. 2020. It would go through the vacuum cycle, try to seal, then repeat the vacuum cycle. I couldn’t get it to stop other than turning the machine off. After turning it off, the vacuum would eventually leak down enough so that I could open the machine > This usually took about 12 hours. I tried contacting the company but my phone calls and e-mails went unanswered. I finally bought another one from Ultra-Source. They are pricy, but I believe well worth the extra money especially if you want to package something delicate as they have the gas capabilities.
