The greatest tool ever! I butcher my own elk, deer, antelope, ect and package every bit of it with my food saver. I've had the same unit for 8 years and have packaged litteraly thousands of pounds of meat with it and it still works as good as it did when I first got it!
Tip: Lightly wet the rubber seal on the vacuum every time you use it. It will seal quicker and the seal will last longer.
