I once had a Food Savor machine. The most expensive top model!! It had a cutting tool. It broke. The heater strip had stopped working!! That was the 4th or 5th one!! I had stopped buying Food Savor machines!! Like a cancer that kept coming back, that same problem kept following me!! The heater would even start sealing, then stop, leaving the food loose in the bag!! I was so done with Food Savor machines!! I have a Ziploc machine now.
