I received my 5000 series promptly and it meets all my expectations. This is not my first FoodSaver so I was pleased with the improvements. I like the easy seal of the bag while cutting a current one. I also like that I can see the bag when sealing so I don't waste material. It is a little awkward holding the back to suction and pressing both sides of the start lever but I am getting used to it. I found that if I put a  cookbook under the bag I am vacuuming it is easier.  The overall footprint is smaller than my previous model so I am able to leave it on my counter and use it more often.
