In a small household often falls on residues which have to be stored. So far, I had a cheap device that is sucked only the air from the bag, but does not generate a vacuum. So I have decided to buy the FoodSaver (after studying multiple reviews). And so far, I must say it is worth every penny. The operation is very simple, a Bedienungslanleitung in writing it. With the stainless steel plate, he also looks very good, and you can fold it also saves space and thus accommodates to any countertop. In my opinion, this is important, otherwise dusty the unit back in the closet. The foods are so packed that thus extending the shelf life considerably, due to the vacuum package I have now more space in my freezer column. I would recommend to anyone toying with the idea, is to purchase a "sealer", only advise rather spend more money, but to buy a really good product.
