I wanted to finally have my refrigerator without odors and also had enough of all the plastic containers that needed a lot of space in the refrigerator. Have ordered the sealer and hoped that it would be right. Well, must say it was the best idea I've ever had. I was pleasantly surprised at the simplicity and effectiveness of the device. It pulls from almost all the air and creates a stable weld. Really a top device that the name FoodSaver really deserves. I sweat so almost any food and am very excited and happy. There is nothing thrown away and thus also saving money. So for me and my household, it was a worthwhile investment. I do not want to miss this device. Even my sister would like to have the unit now because they have seen it with my own eyes how good it is. I recommend it and can only say, you will be thrilled.
