I’ve had FoodSaver vacuums for years but this one has just been a lifesaver! Being retired and with the cost of groceries increasing, it seems daily, having this unit had saved me so much money. I live alone but because of the FM5200 I can purchase in bulk which is a huge money saver. Also it preserves food so well. When I used to use the individual zip lock type bags, even if they were advertised as freezer bags, food, especially meats, would crystallize so quickly and I ended up wasting so much food. With the FoodSaver I have never had an issue.
