I am glad that I waited and got a chamber vacuum sealer. This one works like a charm. I found that, since I am at 4200' altitude that the gauge just barely makes it into the green, so I set the vacuum time to 35 minutes. I bought both the 6 X 8 and 8 X 12 bags, but use the 6 X 8's the most. Make sure that you order the chamber bags, because the regular sealer bags won't work.
