I also have both the FoodSaver (FS) and the Pump-N-Seal (PNS). I don’t use the FS at all any more. Had some trouble with the FS bags leaking. The only thing I put in bags is fresh meat. Although you can vacuum seal zipper bags with the PNS, I prefer the commercial quality “vacuum barrier” co-polymer bags and use a heat sealer and the PNS to do a real professional job. These vacuum barrier bags are thicker, reusable and don’t leak. I bought the PNS, 1000 vacuum barrier bags and the commercial quality heat-sealer for less than I paid for 8 rolls of FS bags. I use the PNS 99% of the time on ordinary jars and any of my own pots, pans or bowls (any size) using the Bowl-Seal accessory. Best of all the PNS creates about 20% stronger vacuum than the FS. Donna should try the PNS.
