This vacuum sealer earned The Best rating from the Hammacher Schlemmer Institute because it quickly created an airtight seal that preserves food 5X longer than typical storage. The Best model removed all of the air and sealed bags in only eight seconds, more than 2X faster than lesser vacuum sealers that required 20 seconds. The Best Vacuum Food Sealer produced a perfect seal that prevented freezer burn on pork chops, fruit, and vegetables and it has a built-in serrated blade that cuts sealed bags open. The vacuum settings adjust to ensure a proper seal for moist or dry foods and the device automatically senses and grasps onto the bag and shuts off automatically when complete. A marinating container (not included) attaches to The Best model and quickly infuses marinades into meat. Includes three one-quart and two one-gallon plastic bags; includes one 11" W x 10' L roll of plastic bags that can be cut to any size. 10" H x 17" W x 5 1/2" D. (11 1/4 lbs.)
