@tampalady I have had a FoodSaver since the mid 80s and LOVE THEM. I would not be without one. Mine have lasted a very long time. I'm only on my 3rd since around 1985! I purchase my rolls at Sam's Club when they have a sale. I use the big rolls that they show with the TS and the 8" ones as well. Making your own bags is SO EASY, as is using the unit. I will tell you that I have NEVER experience freezer burn using the Foodsaver and have recommended it to many friends, who agree. I purchase meats, chicken, salmon, etc on sale and into the freezer it goes once I portion out what I want and then seal it. I can't say enough good things about it. You can even freeze baked goods because you can stop the unit from suctioning the air when you want which prevents crushing.
Also, sometimes we will purchase a large block of cheese at Sam's Club, cut off a piece and then I'll Foodsaver the rest for when we need it and stick it back in the frig.
I have a unit similar to this one but not exactly the same.
EDITED TO ADD ... I would hope this wouldn't make a difference but I bought my last 2 directly from Foodsaver. They have sales all the time.
