I had a food saver prior to the one I just bought because I thought it had broke. To my surprise it wasn't the machine that was not working, it was a roll of bags that for whatever reason would not seal. I was having the same problem with the new one and that is when I discovered the problem. Now with non defective bags the food saver is totally awesome! If you don't have one, get it and you will wonder why it took you so long to order it!
