This sealer is the easiest one to use. You literally just click a button to seal or cut the packaging. In seal only mode, the unit is completely silent and you are notified that the bag is sealed by the light going out. When you use the vacuum and seal function, it’s still fairly quiet. I love how convenient it is to separate meats that we buy in bulk, and how handy this is for marinating foods too! I have been using this appliance almost daily.
