We got this item as a gift.  It does work as directed but we were used to one of the 1st basic models out there - which I would rather have.  We find machine has to be placed against wall otherwise it slides when trying to seal bags.  You must have 2 hands to seal bags - so if you are disabled with 1 hand or have bad arthritis this machine is difficult to use. The product saves on the amount of bag use & you can seal & cut all in one. If the bag is slightly short you will have to hold bag up or prop on something so you can push the bar in with 2 hands to seal, or easier - make a new bag (wasted bag).  Please note I do like food saver products and would buy another, but my husband or I would not buy this model.  Another note - look at dimensions this product takes up a lot of space depending on your storage.
