I'm told that the FoodSaver V4865 2-In-1 Vacuum Sealing System keeps food fresh up to 5x longer and saves up to $2700 per year based on buying in bulk, on sale and preventing waste. I have not had this Food Saver long enough to actually verify these statements, but I will come back in a few months and let you know what I think.
Features of the 2-in-1 Sealing System
::Built-in retractable handheld sealer seals zipper bags, canisters, containers and marinates food in minutes
