An indispensable tool in any kitchen. I give you the reasons: There is evacuated conservation bags of food, preventing the growth of bacteria, mold and spread of odors in the fridge. Life food is multiplied with their freshness and aroma. A food smell the aroma of its own, not that of the food alongside which it was stored. You can make purchases for longer, in the knowledge to eat fresh. Make saving time and money. Having a clean refrigerator, in which there will be no mixing of odors What food have stayed. We always have something on hand in case of unexpected visits. More cleanliness without paying foods by poor handling, and cleaning of the refrigerator is made in a jiffy. In short, a machine that makes life, makes it more enjoyable life in the kitchen, especially for those who do not like to linger. It comes with a connector cable for evacuating the jars designed for this purpose, sold separately, and 5 bags large and small 5. But the bags can be kept longer if they are cut a little larger so as to reunite them. In addition they can wash in the dishwasher, extending their life. Except if used to pack raw foods, such as meat. They are resistant with their smooth texture on one side and the other dotted texture. A nice design for the device, fast welding, easy to use. Maybe a little bit noisy, but not too much. I tried to weld packaging bags that I use in cooking and much soda, even if not of the same brand. Top No? Buy yours quickly. You will be delighted!
