This is the personal vacuum sealer rated best by the Hammacher Schlemmer Institute for its ease of use and long-lasting seal. The Best Handheld Vacuum Sealer’s pistol grip, small size, and simple operation made it easier to use than conventional countertop models that require dedicated space. It comes with 12 quart-size and 12 gallon-size bags with integrated valves; the bags did not leak during testing. The Best model vacuums out air from a bag’s valve in seconds to lock in food’s freshness while leaving the bag's mouth closure intact, allowing you to re-open and re-seal the bag when needed, while typical models require heat to seal a bag's mouth and scissors to open a bag. The reusable BPA-free bags are safe for freezing, boiling, and microwaving. Heavy-duty rechargeable NiMH battery recharges in its storage base, and seals 30 bags on a single charge. 8" H x 6" W x 2½" L. (4 lbs.)
