I also have the Food Saver Brand, V4800. Have had it for about 6 years and love it. I use mine also to reseal bags of chips and the plastic bags of frozen foods. I bought less expensive bags on Amazon and even though they are lighter weight they work perfectly. If I could buy a second one I would try to find one that opens to you lay the bag on the sealing rod instead of sliding it in the slot.. Had one years ago and not sure they even make that model any longer.
